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.

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.
