3076. A 1.5-year-old hamster's tumour grows bigger and bigger fast. How Toa Payoh Vets remove a tumour.

May 20, 2017

Hamster owners in Singapore do surf the internet to look for hamster vets to operate on the pet's tumours as illustrated in this case. "The tumour was small at first," the young man said. "But the vet did not do any surgery even when it grows fast."

This tumour is large at 1.5 cm x 1.5 cm x 1.0 cm. Therefore the anaesthetic risks are much higher as it takes a longer time to operate as compared to a small one at 0.5 cm. All was OK as the hamster recovered and went home.

Case 2. Egg binding. 5 eggs. No eggs laid as oxytocin injections were requested by the owner >4 weeks after egg-laying behavior. .

3073. A 19-year-old red-eared slider has swollen limbs

Written by Intern Wong Shu Yu


A 19 year old female red eared slider was limp and unresponsive when brought in.  The owner mentioned that the slider had not been eating for weeks and that she was gasping for air earlier that morning. As no reflexes were detected in response to stimuli, the slider was pronounced dead. It was noted however, that the slider’s limbs and neck were swollen. This was a possible indication that the slider had been suffering from kidney, heart or liver disease prior to death. The slider’s shell was also dented inwards in the centre, which suggested a history of shell rot in the past.

The slider was considered to have lived a long life given that the natural life span of red eared sliders in captivity typically ranges between 15 to 30 years. It is highly probable that the slider had died of natural causes due to old age; however, it would not be possible to pinpoint the precise cause of death without having resort to a post-mortem. Having discussed the various options with the owner, the owner agreed to have the slider sent for cremation.


Date: Sunday, 30 April 2017

Attending physician: Dr Sing Kong Yuen, Dr Daniel Sing


Name: -

Age: 19 years

Weight: -

Gender: Female

Species: Terrapin

Breed: Red Eared Slider


The slider had not been eating for weeks.  Patient was gasping for air and struggling for air at 2.30am that morning.  Usual diet comprises boiled chicken, prawns, vegetables and commercial pallets.
The slider was exposed to half an hour UV light every day and allowed to bask and dry
off completely.

Physical Examination:

Patient was limp and no reflexes detected
Neck, and limbs were oedematous
Shell was concave in the middle
Carapace measured 16 cm long x 15 cm across


Patient had passed away upon arrival. Cause of death is likely to be old age.
Suffered from shell rot previously, thereby affecting integrity of shell
Edema suggests that kidney, heart or liver diseases could be present

Procedures done:


Treatment Plan:

1. Explained to owner that likely cause of death is old age, but that it is difficult to pinpoint the exact cause of death unless patient is sent for a post-mortem at the government vet facilities. However, some owners find the process traumatic.

2. Owner appeared to be affected by patient’s death, and asked if the patient could have been saved had he sought treatment earlier. Advised that (i) the patient was considered old given that the natural lifespan of red eared sliders in captivity is about 15 to 30 years, and that (ii) treatment options for red eared sliders were limited. Consequently, it was likely that there would be no difference in the
outcome even if earlier treatment had been sought for the patient.

3. Provided owner with option of cremation. Owner agreed and the carcass of the patient was left in the clinic and arrangements made for cremation.

3072. An 8-year-old cat's annual health screening

Written by: Intern Ms Wong Shu Yu

Tammi is an 8 year old local tabby cat who came to us for her annual checkup and vaccination. While there were no significant abnormalities detected upon physical examination, it was noted that Tammi (standing at 4.6kg) is fairly overweight for her size. This puts her at risk for fatty liver disease. An examination of Tammi’s mouth also revealed signs of gingivitis and an ulcer on the upper side of her gums.

The annual vaccine was given to Tammi and blood taken for purposes of testing for liver disease. Other procedures performed included dental scaling, ear cleaning and anal sac expression. Notably, the expression of Tammi’s anal sacs produced a black-coloured substance, which indicated that the glands have not been expressed for a prolonged period of time.

Tammi’s owner was advised to switch to a weight reduction cat food formula in order to bring down Tammi’s weight to a healthier range. The results of the anal sac expression were also shown to and its significance explained to the owner. Dr Sing highlighted that the anal sacs need to be expressed regularly in order to prevent inflammation and subsequent self-injury perpetrated by the animal on the affected area due to discomfort.
