Skin problems no more.

My cat was always overgrooming 24/7 and had spots of missing hair. and I thought he had an ear infection when really it was skin issues - I was so frustrated but then the vet recommended this. His hair is so shiny and it's all grown back and his excess grooming has stopped! he is also FIV positive and seeing the reviews for kidney problems makes me hopeful since he just started having some. He has no teeth so I do half kibble and half water and he likes it!

The formula has changed

My cat has IBD, and the previous formula works for more than 2 years. Now with the new formula, the diarrhea is back, not sure what has changed but it is bad

My allergic cat ate this for 11 years until he had cancer and won his wings. Now my two sweet rescues eat it too. Yummy!

It works!

It works like no other. My cat has a very sensitive digestive system and would often vomit her meals; however, when I started feeding her Royal Canin Selected Protein cat food, there was immediate improvement in her overall health.

My cat tolerates it!

My cat has been through more foods than I can remember due to multiple food allergies/intolerances. There were several we got by with for 6 months, but he’s been on this one and doing well for a few years now! So happy to have food for my senior kitty with a sensitive tummy that he can keep down!

Great help.

We had a stray cat show up and she kept getting ear infections. Finally. we got a new vet and she suggested we try this food as she might have allergies. Hannah has been on this for several years and never had another problem. Thanks for the help!

My cats are soft like bunnies!

One of my cats has skin allergies and since my cats free-feed I give them both PD. Totally eliminated the allergy symptoms and the low ingredient food has had the added benefit of thickening both cat’s coats so their fur is bunny-soft!
