Food allergy in cats: running a diet trial safely

Dr. Jason Pieper on food allergy as a cause of feline overgrooming, the risks of food trials in picky cats, and how quickly cats flare on challenge.

Updated · VetOnIt

Food allergy is worth looking for

In the study of overgrooming cats discussed in the lecture, food allergy was a common underlying cause. [1]

Food trials in cats are worth doing but need care, because a cat that refuses a new diet risks hepatic lipidosis. [1]

Reading the challenge phase

Cats flare faster than dogs after a dietary challenge: in the study cited, about a quarter flared on the first day and roughly 90% within a week. [1]

Adding several new ingredients day by day during the challenge makes it hard to tell which one caused a flare. [1]
