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.
