Mario is an easy going, affectionate adult neutered male who may prefer to be the only pet. When he arrived we noticed he was having some troubles in the litter box so had him checked out and found that he had crystals. He is now on a specific diet to manage the condition and so far so good. If you're looking for a good natured, affectionate house cat, and don't mind getting a vet exclusive diet, then you don't want to miss out on Mario!
