There is more to choosing a litter tray than pulling one off the shelf at your local pet store. Litter trays are available in all shapes and sizes from the standard plastic rectangular tray to customised trays which are hidden in furniture.

Litter tray basics
- Provide one litter tray per cat plus one additional tray. Two trays for one cat, three trays for two cats, four trays for three cats.
- Place litter in different locations and at least one tray on every level.
- The ideal length of the litter tray should be 1 to 1.5 times longer than the cat.

Spraying and toileting behaviours are the most common behavioural problem in cats and a leading surrender and euthanasia. While we humans consider it a problem, it is quite normal and is their way of marking their territory. Naturally, this behaviour is seen as anti-social to humans and thankfully most household cats don’t need to mark their territory.
Sometimes your veterinarian will request a urine sample. Urine can give a lot of information on a cat’s health status. If you have a diabetic cat, you may be required to monitor your cat’s urine at home.
Inappropriate urination in cats is one of the leading reasons why cats are surrendered to shelters. It is frustrating to pet owners, but there is always a reason why cats do this.
