Cat losing fur from allergies? Need cheaper hydrolyzed protein food!

Hello and thank you for reaching out to Boop by Petco. I'm sorry to hear about Kimmie's skin issues, but your veterinarian is correct in recommending this diet trial. You may be able to order the food through Chewy.com for cheaper than other places. They often have discounts for your first order, which can be really great. I would not change the diet your veterinarian prescribed, as this will defeat the purpose of the diet trial! I hope this is helpful!

What's in hypoallergenic cat food for cats with food allergies?

Thanks for using Boop by Petco! What exactly is in the hypoallergenic diet is somewhat dependent on which one you get. However, generally the idea is using a smaller protein that it is easier to digest. There is usually a good amount of antioxidants and vitamins as well. All in all these types of diets can help tremendously in patients with food allergies. There are many of them out there. My favorite is Royal canin's ultamino diet. Good luck and have a great day!
