"I have a 5 year old Siamese cat who has a very sensitive stomach. He was on the Casto & Pollux indoor cat dry food until about a month ago. He had an upper resp. infection and had lost his appetite, had lost weight. The vet suggested trying to get him to eat moist food. Stating that he could smell the wet food better and might entice him to eat. So, trusting Castor & Pollux - I bought the canned version of Natural Ultramix for indoor feline. Boy, this saved my cats life!! He loved it and has gained back some weight. Also, he would on occasional vomit the dry food related to the carrots. He has not vomited since being on the canned food. The only problem is now he won't eat the dry food - he meows and meows for the canned food!! So, I will be buying this product by the case."
