Pearl's been fine ever since she's been eating Innova Evo. I guess it must be grains in other cat foods that she's allergic to although I did try another brand of grain free food that also had some fruits and vegetables in it and she did end up breaking out. My cat Starr has IBD/colitis so he also has to be on a grain free diet and he also didn't do well on the other brand. So I'm sticking with Innova Evo.

The first time that Pearl broke out the vet I used to see gave her a depo shot and she became very sick from this. She developed a bacteria infection so if she ever breaks out again she'll get prednisolone. I had it compounded into a liquid form because she's also very hard to pill. You might also want to try buying some Pill Pockets to help hide the pills. You can buy them at most pet stores or your vets office. I use the chicken flavored ones every day for several of my cats and they love them. They just think that they're getting a treat. I cut them up into 4 pieces and then wrap the pill pocket around the pill. It's very soft and pliable.

I also took Pearl to a holistic vet and she was fine at the time but she said that if she ever breaks out again I can go to Whole Foods and buy Gaia which is a licorice root herbal liquid. It's the low alcohol (glycerin) formula and you give .5cc by mouth daily for 14 days when needed. You can also buy it online. She's been fine ever since so I never did try this. I know that she said that it would take a bit longer for her to clear up with this than with the pred.

Pearl's never had breakouts inside of her mouth. It's just on her lips. She starts by breaking out on her chin so I just thought she had feline acne at first. Then within a few days she broke out on her lips and she wasn't eating very well. I took her into my new vet and sure enough she had eosinophilic granuloma complex or EGC. I also tried giving her some lysine but it was hard to give it to her and she also started having a lot of diarrhea so I stopped. I hope that your cat will start feeling better and that hopefully a diet change will also work for him. Good luck.
