Chip has FIC (Feline Idiopathic Cystitis), which basically means he doesn't take in enough fluids, especially when he is stressed. This cause his bladder to become irritated, which can result in not using the litter box appropriately. Because stress is a major component of this problem, he is not a good candidate to go to PetSmart. This condition is usually very manageable in a home setting by simply encouraging water consumption by adding a fountain for him to drink from and feeding canned food on a daily basis.
