Vancouver Feline Hospital - Cat Veterinary Clinic

9. Make any changes in your cat's routine, including diet changes, very slowly.

10. There are sprays and room diffusers (Feliway) that your veterinarian may recommend in an attempt to decrease "environmental anxiety". Such sprays can be used in the environment close to the litter box, food and water bowls, in areas that the cat likes to "hang out". Your veterinarian may also recommend drugs in highly stressed cats. Drugs will not work alone!

11. Books to help the owner understand the nature of the cat and contribute to a more normal environment for the cat. Some recommended are:
From the cat's point of view - by Gwen Bohenkamo
Felinestein: Pampering the Genius in Your Cat - by Delzio and Ribarich
Catsmart, and The body language and emotion of cats - by Myrna M Milani, DVM
Twisted Whiskers - solving your cats behaviour problems - by Pam Johnson

12. Finally: Cleaning: use enzymatic cleaners (lots of it!), machine wash all that can be washed, discard any cushions or carpets that urine has soaked into. Cats have a much better sense of smell than humans, and even if you think its clean, chances are the cat still thinks it stinks like a toilet. Prevent: You HAVE to provide an acceptable alternative and meet the cats needs before making the problem area unattractive (by using citrus scents, covering with industrial heavy plastic) - otherwise the problem will not resolve. Remember too, punishment will worsen the problem - reinforce good acceptable behaviour with love and encouragement -reward.Making the changes suggested above, increasing water intake and appropriate medical treatment are all essential - ensure your cat does not have any untreated medical condition that can cause this problem!
