What to Feed an Old Cat

There are many physiologic changes that occur with aging that compromise the ability of the body to respond to stress or change.  Dietary management is critical to the outcome of some disease (chronic kidney disease, obesity, diabetes, hyperthyroidism--commonly seen in cats).  The aging process is  not uniform and affects each cat differently.

Researchers are only just beginning to explore the ptential impct of nutrition on the physiology of normal aging in companion animals.  In dogs, there is a huge difference among breed types; breed related differences have not been reported in cats.  Studies in humans and dogs have shown a decrease in needed calories with age.  There is evidence in cats that there is a gradual decline in needed maintenance calories until 10-12 years of age.  After this, an increase in needed calories is generally experienced.  Altered digestive capacity may be a factor, along with decrease activity by the cat.

Recent studies have shown that dietary supplements of antioxidants, fatty acids and a prebiotic fed to senior cats can potentially increase their lives by an average of a year.  Other significant findings includes a higher blood level of Vitamin E and improved red cell counts (less anemia), improved body weight and skin thickness.

Bottom line..older cats should be addressed as individuals, including an assessment by your veterinarian. I recommend a physical examination in all older cats (dogs too!) every six months with blood work for assessment of body organ function, every 6 - 12 months depending on the individual and their specific general health concerns.

As we increase our understanding of the aging process, we gain greater insight inot the nutritional needs of our older pets.  Cats have unique nutritional requirements no matter what age they are, but older cats are especially challenging.  Antioxidants, essential fatty acids and prebiotics all seem to have some benefit to the older cat.
