I'm sorry to hear this. I feed my cats both wet and dry Innova Evo and so far they haven't had any problems. Sometimes if Ziggy eats too much wet food she will have some loose stools but it's not diarrhea.

You can also try giving her some canned pumpkin. Some cats won't eat it so you could try to mix it with some wet food. I've heard that it's good for both diarrhea and constipation. She may need to have a food that contains rice in it so it'll help keep her stools firm. I hope that she'll get better soon. Good luck.

I also wanted to add that my cat Starr was having severe diarrhea and now he's on some herbal supplements as well as his pred and he's been doing very well. Maybe Magic needs to have some probiotics added to her food. Starr is currently on primal defense powder. I give him one scoopful once a day and I give him half of it in the morning and half of it in the evening mixed in with his wet food.
