Part 1/2. A friend in need is a friend indeed.
Part 2/2. How to remove a sewing needle inside a cat's mouth during a house-call.


Part 1/2 highlights that the proverb "A friend in need is a friend indeed" does apply to feline behaviour too. 

Part 2/2 discusses about the treatment - how did I extricate the needle inside the aggressively angry cat's mouth during a house-call

-------------------------

PART 1/2 VIDEO.

FIFTEEN YEARS AGO, in July 2010, Mr Hall from the Grand Hyatt, Singapore was badly scratched when he tried to open his brown cat's mouth to pull out the sewing needle and thread. He phoned Toa Payoh Vets for a house-call. My two veterinary assistants, Mr T T Aung and Mr T H Saw kindly volunteered their Saturday evening to help me.

In Part 1/2, the illustration by ChatGPT showed a scene in which Mr Aung was holding the partially sedated cat for me to open the cat's mouth to examine. Suddenly, a grey-white cat hissed loudly. Before we could see him, he had leapt up high, pouncing onto Mr Aung's backside and legs.

Script written on 27 Feb 2025.
Part 1/2. A friend in need is a friend indeed.

Mr and Mrs Hall lived with two cats in a 2-bedroom suite in the Grand Hyatt, Singapore. 

 His brown cat had his wife’s sewing needle inside the painful mouth.

The cat scratched Mr Hall’s hand to prevent the needle from being taken out.  

Mr Hall phoned Toa Payoh Vets for a house-call as his cat would not go inside the cat carrier to be transported to Mr Hall’s veterinarian. 

In this Part 1/2 video, Mr Aung had scruffed the brown cat’s neck and was taking him out of Bedroom 2.   

Suddenly, a grey cat leapt high up towards Mr Aung’s back as he walked towards the table in the living room. 

His hisses spilled drops of saliva out of his mouth. He extended his front paws and sank his claws into Mr Aung’s back.

Gravity pulled the feline attacker on to the floor. However, he managed to sink his claws onto Mr Aung's backside and black pants. Mr Hall quickly carried him out to the living room.

Mr Hall announced: "The cat is trying to protect me!".

I did not reply but I knew the cat attacked Mr Aung to save his companion who was drugged and incapable of movement.

“A friend in need is a friend indeed” is a proverb meaning “a person who helps at a difficult time is a person who you can really rely on.”

This proverb applied to cats too, as evident in the second cat attacking Mr Aung to help his sedated feline friend.

Part 1/2 video shows that the proverb "A friend in need is a friend indeed" does apply to feline behaviour too. However, Mr Hall attributed the behaviour to the cat attack as the cat trying to protect Mr Hall.What do you think?

VET CASE STUDY:
Wed 7 July 2010

A needle and thread inside a cat's mouth - 5 July 2010

Going to an apartment to treat a ferocious cat with a needle and thread inside his mouth is like going to a lion's den. Mr Hall said: "I am sorry I am unable to place my cat inside a crate to bring him to your Surgery as he claws me! I had tried to open his mouth to take out the needle but he clawed me many times!"

So I had to make a house-call on a fine weekday evening to Grand Hyatt where Mr Hall lived as he was the Senior Manager. My two assistants, Mr Aung Thein Tun and Mr Saw Thet Htun who was on leave met me at the lights-down lobby. The hotel guard took us in the elevator up to his unit.    
 
AT THE SCENE
 
Mr Aung is a hands-on man with no time to waste. This cat was crouched tightly inside the master bathroom between the water closet and the wall. He grabbed its scruff, grabbed him and placed him on the cat's white towel on the bed in the master bedroom. I had not briefed my assistants and was therefore surprised.

"It is best to prepare the sedative before catching the cat," I said to Mr Aung. "Look at the cat to estimate his weight and prepare the correct dose."

The cat was displeased and pawed Mr Aung vigorously. Mr Aung released him. The cat bounced off the bed and went under the master bed. There was a moment of indecision as Mr and Mrs Hall and I did not know what to do.

"Maybe Mrs Hall should under the bed to get the cat out," I said like a General who barked orders from the safety of an army headquarters far away from the battle scene. Nobody moved.

"Let's lift up the bed," Mr Hall suggested intelligently. Mr Hall and my two assistants lifted up one end. I helped. It was surprisingly a very light bed but there were four of us. Mrs Hall looked on.

Being exposed, the cat sprang to hide behind the day curtains. The room has two sets of curtains. The day curtains are the translucent type. Mr Aung walked quickly towards the curtains to make friends with the cat. What he does normally is to talk to the cat and slowly let the cat (or dog) get used to the smell of his hand. The cat was ready to scratch him as he had scratched Mr Hall's hand a few times when Mr Hall tried to open the mouth to take out the needle.

ARMING THE TROOPS FOR BATTLE

"Prepare the sedative first," I said to Mr Aung. That would be what I would do before touching the cat. I estimated the cat to weigh 3 kg. Though he was adopted as a local cat, he certainly was bigger and fatter than the stray cats we see around the neighbourhood. Mr Aung got 0.1 ml Domitor and 0.1 ml Ketamine in one syringe and gave it to me. He realised that this cat would never accept an IV injection. IV injections at the Surgery could be done because the cat would be in foreign territory and would not be so ferocious usually. Here, the cat was on home ground.

FRONT LINE DANGERS
Being a hands-on man, Mr Aung never hesitated from feline dangers. He walked on his tip toes and squatted swiftly in front of the day curtains. In one speedy grab, his right hand gripped the cat's scruff. He placed the cat on the white towel on the master bed. I was ready with my syringe and in less than one second, I had injected the cat's backside muscle with 0.2 ml IM of the combined sedative. Mr Aung let go of the cat.

UNDER-DOSED
It is always safe to under-dose a frightened cat. I knew the dose was insufficient. For the next 5 minutes, the cat ambled out of the master bedroom, dashed across the living cum dining room with the open concept kitchen and disappeared into Bedroom 2 at the other end of this apartment. Another 5 minutes passed. The cat was as fresh as a daisy.

REINFORCEMENTS
In a losing battle, the commander must call for reinforcements. "Give the cat Domitor IV," Mr Aung proposed catching the cat as he was one never afraid of getting cat scratches. "All three of us are veterans with cat scars on our hands" I had said to assure Mr Hall who must be wondering what was going on. The sedative seemed to be like a dud missile that fell and did not explode.

CAUTION
Soldiers could shock and awe in battle with more bombings to kill the enemies. But this is a cat that must be alive at the end of the house-call. "Better not to give another sedative," I advised Mr Aung. "The cat may react and die. Just wrap the cat inside a towel with his head sticking out. That would be safer."
 
The cat would be sedated slightly as 15 minutes had passed." I asked Mr Saw to take the white towel from Bedroom 1.
 
"SUICIDE BOMBER" ATTACK
Mr Aung went inside Bedroom 2 to risk his hands and got the cat by the scruff of the neck. Mr Hall and Mr Saw and Mrs Hall were inside Bedroom 2. As the room was small, I stood outside the door to supervise.

While Mr Aung was holding the cat for Mr Saw to wrap the towel around, the second cat, white with grey patches suddenly leapt up to claw Mr Aung's back legs. I just could not believe this suicide bomber attack. This attacking cat hissed and swung his paws widely. He leapt up but gravity pulled him down. From my point of view, he had attacked Mr Aung to save his companion.

In cat attacks, it is wise not to interfere. Water hosing would be ideal but not inside the apartment. Mr Hall managed to get the attacker out of the room. The brave feline slinked outside the room and would not go away. He was just so furious. Was it the attention the other cat was getting? No, he was trying to save his friend.

Mr Hall said to me: "This cat is very protective and was protecting me." Well, next time, no other cats should be present.

The next day, I noted that Mr Saw's left hand had two cat scratches too when we were taking blood from a dog. So, Mr Saw had suffered too.

ACTION
After wrapping the cat in the towel, the cat seemed quiet. I said to Mr Saw: "Put the cat on this kitchen counter." I gave Mr Aung the forceps from my bag. He opened the cat's mouth. "There's the needle stuck in the hard palate!" he showed the object.
 
I took some pictures with a zoom lens which was not appropriate as a wide angle lens would be preferred. The zoom lens could not focus until I stepped back further. 
 
Mr Aung took the needle out. A black thread with slimy saliva was attached to the end of the needle. I should have put the needle onto the tissue paper as Mr Hall seemed not too pleased when I placed it directly onto the kitchen counter. Mrs Hall took away the needle. I opened the cat's mouth to give a final check. "No injuries or ulcers," I said to Mr Hall.





ANTIDOTE
house call at the Grand Hyatt Singapore. A cat swallows a needle and thread, toa payoh vets singapore"Should give Antisedan," Mr Aung advised me. "Antisedan is an antidote," I said to Mr Hall. "The cat will wake up immediately. If Antisedan is not given, he would wake up fully over a few hours. Which do you prefer?"

"It is better that the cat be sedated for a while," Mr Hall said.

"There is a small risk that the cat may not wake up. A very small risk. Antisedan injection ensures that the cat's heart and lung systems are back to normal promptly."

The cat inside the towel hissed and hissed. Mr Hall agreed to the Antisedan injection. This was given via the cat's femoral vein at 0.1 ml IV. "Take the cat out of the towel and put him on the floor," I said to Mr Saw rather urgently. 
 
Mr Saw could not understand what I mean. In any case, he had no time to think. The cat looked up, assessed his situation well. The cat crawled out of the loosened towel, stood on the counter and in one spring, he leapt onto the floor and disappeared into the sanctuary of the master bedroom.

HAPPY ENDING
Everybody was happy that this cat was back to normal. Most important, the cat survived an anaesthetic.

Mr Hall asked me for my name card as he was surprised that I was prompt in answering his house call. Mrs Hall would be more careful with her sewing needles and threads from now on.

CONCLUSION
Never give the frightened cat a second dose of sedatives as the cat may just die. This case took three times as long but the cat was alive and that was what every owner wants. It is best to treat such cases at the Surgery. Normally I don't even want to do it at the house as there are so many complications and surprises. Besides, it takes a longer time.

RE-ORGANISATION
After a battle, the soldiers will re-group and review. In my case, I said to Mr Aung and Mr Saw that Xylazine 20 + Ketamine 100 @ 0.1 ml + 0.4 ml respectively in one syringe IM would be more effective for this <3kg cat as a sedative compared to Domitor 0.1ml + Ketamine 0.1 ml IM. There are many ways to sedate a cat and since Domitor was chosen and it was one of the recommended sedatives, I had to respond to the challenges involved when the cat was full of beans after the Domitor injection and ambled off. Mr Hall must be thinking that the vet was inexperienced as the cat was not 100% knocked out.

We all learn from hands-on experiences in real situations. All theories about anaesthetics are excellent but the realities of the situation can be so much different and in this case, quite painful for Mr Aung and Mr Saw as they were scratched and attacked by the suicide bomber cat. 

A cat in pain and fright is as dangerous as a lion if you had been present in Mr Hall's apartment when I was doing the house-call. Sedation dosage must be minimal as the cat was highly stressed. A calculated normal dosage could kill the cat in such situations. Hence, I under-dosed him.

I still can't believe that there was a suicide-bomber cat digging his claws into Mr Aung's hands and fighting off Mr Saw's intervention. If the case was handled at the Surgery, it would have been much more safer for the feline patient and the vet assistants!

4470. PHOTOGRAPHY TIPS: How to take attractive photos of The Merlion?

 

Get advice on how to take attractive photos of the Merlion statue in Singapore
 
 
 

 
 
 

Taking stunning photos of the Merlion statue in Singapore requires careful planning, the right angles, and good lighting. Here are some expert tips to capture the best shots:

1. Best Time for Photography

  • Golden Hour (Sunrise & Sunset): The soft, warm lighting enhances the beauty of the statue and the Marina Bay skyline.
  • Nighttime: The Merlion is illuminated, and you can capture stunning long-exposure shots with the Singapore skyline in the background.

2. Best Angles & Perspectives

  • Classic Front View: Stand at Merlion Park and capture the Merlion with Marina Bay Sands in the background.
  • Side Angle with Water Spray: Position yourself to capture the water jet from the Merlion’s mouth, making it appear as though it’s reaching Marina Bay Sands.
  • Low Angle: Shoot from below to make the Merlion look majestic against the sky.
  • Wide Angle for Cityscape: Use a wide lens to include the Merlion, Marina Bay Sands, and the Esplanade in one frame.
  • Creative Forced Perspective: Play with angles so it looks like you’re “catching” the water spray in your hands or drinking from it.

3. Camera & Settings Tips

  • Use a Tripod: Essential for long-exposure shots at night to avoid blur.
  • Adjust Exposure: Bright lights from Marina Bay can trick your camera into underexposing the Merlion. Adjust brightness accordingly.
  • Long Exposure for Water Effect: At night, use a slow shutter speed to make the water flow look silky.

4. Weather Considerations

  • Avoid Midday Harsh Light: The strong tropical sun creates harsh shadows; use an ND filter if shooting in daylight.
  • Check for Clear Skies: Cloudy weather can reduce the vibrancy of the scene.

5. Additional Creative Ideas

  • Reflections: After rain, puddles can create interesting reflection shots.
  • Silhouettes: Capture the Merlion’s silhouette against a colorful sunset.
  • Drone Photography: If permitted, get an aerial shot of the Merlion and Marina Bay.

Would you like specific recommendations for camera settings or locations nearby for additional shots? 😊

The Canon EOS R5 with a 24-105mm lens is a great choice for photographing the Merlion as it provides flexibility for wide-angle cityscapes and zoomed-in details. Here are specific recommendations for settings and techniques based on the time of day and conditions:


📸 Daytime Photography (Bright Sunlight)

Best Settings:

  • Mode: Aperture Priority (Av) or Manual (M)
  • Aperture: f/8 – f/11 (for sharpness and depth of field)
  • ISO: 100 (to reduce noise)
  • Shutter Speed: 1/250s or faster (to freeze motion, especially the water spray)
  • White Balance: Daylight
  • Lens Focal Length: 24mm for wide shots, 50-80mm for mid-range compositions

Composition Ideas:
✅ Use a wide-angle (24mm) to include the Singapore skyline.
✅ Zoom in (80-105mm) to focus on the Merlion’s details or the water spray.

4469. WILDLIFE SINGAPORE. Smooth coated otters in Potong Pasir 16 Feb 2025

Wildlife Singapore
by Dr Sing Kong Yuen
1 Mar 2025


This video shows:
1. A group of Smooth-coated Otters along the Kallang River, Potong Pasir.
Video was shared by by Mr Chan Jin Lee on 16 Feb 2025 at 7.20pm.

2. A video of the North American river otters (Lontra canadensis) is shown to compare them with the Smooth-coated Otters seen in Potong Pasir Town, beside the Kallang River.  The North American river otters has a thick water repellent fur. An adult weighs between 5 and 14 kg.

The North American river otter has a thick
water-repellent fur to protect and insulate him.
An adult weighs between 5 and 14 kg. It lives
only in the North American continent.

Compared to the Smooth-coated otters in Singapore,
they look much bigger in size and are heavier. Being expert
swimmers, they can swim up to seven miles per hour
and dive down 60 feet.

4. SUMMARY:

Singapore has two species of otters — the Oriental Small-clawed Otter, and a larger species called the Smooth-coated Otter which weighs 7 kg to 11 kg and measures 96 cm to 120 cm in total body length.

The larger smooth-coated otters subsist mainly on fish, and small-clawed otters feed more on crustaceans and molluscs

The former is found along the coast and in larger rivers
while the latter forages within forested mangroves,
ponds and streams. The latter locations are fewer in Singapore
compared to large rivers and reservoirs, owing to urbanisation.

The government's successful clean-up efforts leading to
unpolluted waterways that sustain fish and the wildlife
such as the Smooth-coated Otters that feed and live in them.

The Scientific name for the Smooth-coated Otters is
Lutrogale perspicillata. They may be spotted quite regularly
in groups of two to more than 10 in rivers, reservoirs
and lakes in places like the Botanic Gardens and public parks. 

They have become a pest to private house owners
and others who keep kois and carp fishes in
outdoor ponds. These otters have had eaten all
their valuable ornamental fishes.

The other local species which is the small-clawed otter.
Its Scientific name is Aonyx cinereus. It lives in 
riverine habitats, freshwater wetlands and mangrove swamps. 
It feeds on molluscs, crabs and other small aquatic animals. 

As Singapore has fewer forested mangroves, ponds and 
streams than rivers and reservoirs, it is rarely spotted in public
housing towns such as Potong Pasir.  In any case, it will not have its
preferred small aquatic animals. However, this species 
is seen in the Mandai Wildlife Reserves Zoo.

 

Otters smell pungent, particularly near where they leave their spraints (otter defecation) to mark their territory on land. If you spot otters, do not touch, chase, or corner them, as this may frighten them. Instead, watch them from afar.

4468. Vet Case Study: Femoral head ostectomy dog myanmar

4467. Femoral head ostetomy

Vet Case Study: The Pomeranian cannot put down her painful left hind leg. What to do?


This Be Kind To Pets veterinary educational video is sponsored by Toa Payoh Vets. The script is written by Dr Sing Kong Yuen, BVMS (Glasgow) on 19 February 2025.

This video explains one treatment of a hip dislocation in a 5-year-old female Pomeranian in Myanmar by Dr Thet Hmue Kyaw, BVSc (Yezin).

The Femoral Head Ostectomy (FHO) is a surgical operation to remove the head and neck from the femur.

It is performed by vets to alleviate pain in the hip  in the dog, cat  and horses. Pain hip can be caused by hip dysplasia, dislocations, fractures and arthritis.

The head of the femur bone is removed using a small saw or a bone hammer and chisel.

The hip joint is left without a replacement femoral head. There is a pseudoarthrosis (also called a "false joint").No more bone to bone contact causing painafter FHO.

No more bone to bone contact causing painafter FHO. The dog is able to walk normally one to two months after FHO surgery.

The cost of the FHO surgery in a small breed dog such as the Pomeranian in Singapore can be S$6,000 or 9,392,340 Myanmar Kyats.  

The Pomeranian had the FHO done recently. The follow-up one month later is not due.

4466. The yellow-barred flutterer returns to YCKC forest after several months of absence.

 
 
18 Feb 2025:
