Inflammatory Bowel Syndrome

Does anyone know anything about inflammatory bowel syndrome in cats?

The cause of IBD is poorly understood. In fact, it appears that there may be
several causes. In most instances, an underlying cause cannot be identified.
Whatever the cause(s), the end result is that the lining of the intestine is
invaded by inflammatory cells. An allergic-type response is then set in
place within the bowel lining. Many vets and pathologists believe that
bacterial and/or dietary proteins may stimulate an autoimmune type of
reaction in these cats. This reaction, in turn, results in a buildup of
immune cells on and within the surfaces coming in contact with these
proteins. This interferes with the ability of the cat to digest and absorb
nutrients.

Sensitivity to food antigens contributes to and is sometimes the cause of
IBD in some cats, so a change in diet often provides symptomatic relief.
The first step is to determine whether or not an ingredient and/or additive
is the immune trigger. Try switching to a food that contains no chemical
preservatives and/or dyes or chemical additives (e.g., Nutro Natural Choice,
Nutro Max Cat) - chemicals and dyes are often the culprits.

If that doesn't help, then you may need to try a food elimination trial.
Start with feeding your cat a novel protein - that is, a protein to which he
has not been previously exposed (e.g., rabbit, venison). You may need to
experiment with several different foods until a tolerable diet is found.
Ideally the diet should contain a single source of protein. So-called
"hypoallergenic" diets are rarely truly "hypoallergenic" - unless the
molecular weight of the protein is below the immune response threshold...
unlikely. Homemade diets are an alternative for cats that refuse to eat
commercial products. Your vet can provide an appropriate recipe. Don't try
it on your own! Feline nutrition is *very* tricky - cats have unique protein
(essential amino acids) and fat requirements.
