Review on Royal Canin Persian Adult Dry Cat Food - 3 Lb Bag by Tony Miller

My persian cat was raised on Royal Canin and when I adopted him at 5 years, I fed him the same Science Diet I was feeding my other cat. Within 6 weeks he started having loose stools and gas. YUCK! I took him to the vet who said he had beautiful skin, coat, and teeth. She commented that he must have been well taken care of by his previous owner and that Royal Canin is an excellent product . I switched him back to Royal Canin and everything is good again.Just a side note, I've fed all my other pets Science Diet and always been very happy. It just didn't agree with this little guy.
