Many people worry about their cats getting fat, but unintentional weight loss can be weight loss in cats older serious issue, too. Weight loss can be quite subtle as the cat's coat can make it difficult to see when this is occurring. Many pet foods contain carbohydrates which can have un dramatic impact on the calorie count per serving. If a hyperthyroid cat has his thyroid glands surgically removed or has radioactive iodine treatment for feline hyperthyroidism, then it is possible that after the removal, the cat's thyroid levels may be low, either temporarily or permanently.
Decline in body weight is common in cats that are older than 11 years. Indeed, the maintenance energy requirement of older cats may increase rather than decrease. It has been recognized for many years that both protein and fat digestibility decrease in many apparently normal cats after 10 years of age. While the cause of the decreases remains unclear, the changes are quite marked in some individuals and in particular can be dramatic with regard to fat digestibility.
Methods for such testing are rarely available for evaluation of veterinary patients, even at referral centers. Whatever the explanation for weight loss and decline in nutrient digestibility in older cats, progressive decline in body weight has been reported in the two years before death from a variety of seemingly unrelated diseases. As cats live increasingly longer lives and receive attentive health care, this weight oldre is more frequently recognized.
In this article, I will review what is known about common age-related changes and what may be done to halt or reverse the decline in body weight that is apparently a predictable prelude to death. Well-recognized causes of weight loss in old cats include chronic renal disease, diabetes mellitus, hyperthyroidism, inflammatory bowel disease IBDexocrine pancreatic insufficiency, and dental problems.
Most are readily suspected and confirmed based on weight loss in cats older examination and routine laboratory testing. Despite thorough investigation, however, the underlying cause of even severe weight lose fat crotch weight loss in cats older be remarkably difficult to establish conclusively. Dental disease can contribute weight loss in cats older weight loss in senior cats. Tooth resorption of the left maxillary canine a and 3rd premolar in a cat b.
Small focal areas of inflammation are apparent on the left maxillary 3rd premolar b and the left mandibular 4th premolar c. The left mandibular 3rd premolar is missing, leaving focal residual inflammation d. In weigjt same cat, an intraoral bisecting angle dental radiograph of the left maxilla shows an unsuspected extensive tooth resorption at the cementoenamel junction of the distal left maxillary canine tooth a.

Subtle weight loss may not even be noted unless careful records of body weight and body condition scores are kept over repeated veterinary examinations. Similarly, moderate increases or decreases in food or water intake will probably go unnoticed by most owners.
Even when the most attentive owners provide the best veterinary care for their cats, a substantial proportion of senior cats will weight loss in cats older weight loss, despite being in otherwise good health and exhibiting no lss change in food intake. Evidence indicates that, in these older cats with no apparent classic diseases to explain the weight loss, there is an age-related decline in food digestibility.
Percentage of cats with low fat digestibility by age pooled data from four colonies. Low protein digestibility also seems losw affect mature and geriatric cats. The incidence of low fat and protein digestibility tends to occur in the same cats. Percentage of cats with low protein digestibility by age pooled data from four colonies. After 12 years of age, there is marked decline in body weight among cats, which supplants obesity as a common life-threatening condition.
Overall, while obesity tends to be the predominant body-mass concern in cats between 7 and 12 years of age, in those older than 12 years, obesity is rare and being underweight is a far greater life-threatening risk factor Table 1 and Figure 6. Addressing age-related changes in feline wdight. Proc Nestle-Purina Compan Anim Nutr Summit, Focus Gastroenterol The cause or causes of this cate in nutrient digestibility remain unknown but presumably reflect enteropathy of some type.
In some cases, this intestinal dysfunction may overlap with what is loosely classified as idiopathic IBD. Some cats compensate for the loss in digestive function by eating more and, therefore, exhibit no weight loss.
Is Your Cat Losing Weight?
Skinny old cats : Why some senior cats lose weight. What’s going on? (Sponsored by Purina Veterinary Diets). Continued. Gastrointestinal problems. There are a variety of different conditions in the gastrointestinal tract that may cause cat weight loss. When this is the case. Weight loss occurs when more calories are expended than are consumed. Healthy animals can experience weight loss, but in a geriatric cat, a subtle decrease in weight.
