Hi how would you compare blue buffalo Rx diet HF hydrolyzed canned food to hills Z/d hydrolyzed rx canned diet? Trying to find an alternative to royal Canin Selected protein Rx diets which Trixie will no longer eat .. nor does she like the hills z/d. Thanks

Frankly, I do not care for Blue Buffalo products because they have a history of lying about their ingredients in their diets. Hills and Royal Canin are my preferred brands. There are other limited protein food brands out there, such as Natural Balance, which has formulas with a single protein source and a single carbohydrate source, making it less likely for your cat to develop an allergy.
