What's the best wet/dry cat food for indoor cats with fish allergy?

Thank you for submitting your question regarding Sage. Most over-the-counter foods are contaminated with ingredients not listed on the label. For example, if the diet lists the main ingredient as salmon, there could be small amounts of chicken in the food. This makes it very difficult if a patient has a food allergy. Prescription veterinary diets such as a hydrolyzed or a limited ingredient diet will be most successful for a food allergy. They are more expensive, but in the long run typically end up saving you money. If she is not constantly seeing her veterinarian for exams and medications due to skin disease, this will save you money. Hydrolyzed diets have the protein source chopped into such small pieces that the body's immune system does not recognize and react to it. Examples are Royal Canin Veterinary Diets Ultamino, Purina ProPlan Veterinary Diets HA or Hills ZD. The same companies make limited ingredient diets with one protein and one carbohydrate source. It can be some trial and error to find the best food. I hope this information helps!

Do not combine foods, this causes GI upset. Brands of food I recommend include Royal Canin, Hill's Science Diet, Purina Pro Plan, and Iams. I recommend these foods because they run their own feeding trials, meet AAFCO standards, and have veterinary nutritionists on staff. They are the only four brands to do this. I think an indoor cat formula would be best for Storm. As for water, get a pet water fountain. It provides a constant source of fresh water, and encourages cats to drink. I have one for my cats, and they love it. Don't change litter if he has one he likes. Cats are very picky about litter, and a change in litter can lead to them not using their box.

Your only option is to try another protein source that is easie to find or switching brands. Royal Canin makes a rabbit and pea formula and a venison and pea cat food for allergies. Hills does make the D/D in other variety such as salmon that you can also try. Unfortunately they are all expensive though

If Maze was previously diagnosed with food allergies and they don't seem to be better yet, then they were not adequately diagnosed. First, it can take several weeks for the allergy to go away after a diet change. So, if it's been less than six weeks after the diet was switched, then you'll need to wait a little longer before you know if it worked. Food allergies are due to certain proteins and they are usually animal proteins (beef, pork, dairy, etc.). To find the actual protein Maze was allergic to, you must have done an elimination trial. If there was not an elimination trial done, then you would be only guessing at the source of the allergies. One way I often bypass the elimination trial is by recommending a hydrolysed protein diet such as Hill's i/d. In these diets, the proteins are broken down, so there is minimal chance of them causing an allergy. This would have to be prescribed by a veterinarian though. In the meantime, you may consider starting a diet trial to see if that helps to relieve the problems Maze is having. Here is a link to a good article that explains how to do the diet: http://communityvet.net/2010/03/diy-elimination-diet-for-the-dog-an-cat/ Keep in mind that your diet trial will cease to work if she is getting any treats or table scraps. Make sure that there is no possibility of this happening - especially if there are kids in the house. As always, it's recommended to do these things in consultation with your vet.

The best food for a cat with food allergies would be a prescription diet specifically designed for this purpose, such as Hills z/d or Purina HA. You can purchase these through your vet's office, or order online with a prescription from your veterinarian.

I personally feed Wysong Uretic to my cat who has a history of cystitis (due to food allergies with other products), and she does great on it. I would let your vet know you are looking to try that so they can work with you on a food trial and slow transition to see if it helps improve Sebastian's symptoms. Your vet may recommend a few checkups during the trial period to do so to ensure the food is helping.

I don't think Royal Canin makes a dedicated fish diet for cats. i'm not sure why you are looking specifically for a fish based diet, if it is because you know for sure that he is doing better on such a diet i would recommend ORIJEN Six Fish Cat Food.
