Lynne, if you feed grass fed meat - in this case, venison that was not given any grains - it probably already has the correct ratio of Omega 3 fatty acids. You should inquire of the rancher or supplier how the deer were raised and what they were fed.

If you cannot obtain this information or they were fed grain, then I would agree with MadameAlto. Try to do the elimination diet more strictly and add the fish oil later. And yes, fish oil... salmon body oil, to be precise ... is what you'll want to use if your cat is not allergic to it.

I would hesitate to add even the other ingredients (except taurine) you are adding, as a true allergy elimination diet should contain only one single ingredient and no other foods, including no source of carbs and no supplements. Cats of course can't stay on such a diet long (unlike dogs), so the easiest way to do this effectively is to use a food such as rabbit that can be fed with its bones and organs. This won't work if your cat has had rabbit before, of course. Because otherwise the waters will remain pretty muddied. I like the whole ground rabbit from www.hare-today.com. Primal has also recently come out with a whole ground sardine product that might be a good choice for a cat who has never had sardines.

No matter what, I would add taurine. Even 90 days is too long to risk a taurine deficient diet for a cat.
