We had a cat who would start peeing in the squat position, but would slowly raise his hind end until he finished by standing completely upright and 'spraying' his urine on the sides of the litterbox. Ugh! You should have seen how annoyed I was with myself when I closed the kitties in the bedroom for company being over and only gave them a litter pan. With no hood. Next to my bed. With a comforter hanging over the edge. Right next to the litter pan. *slapped hand to forehead
I learned my lesson the hard way.
Because of Toby, we now use jumbo hooded litterboxes whose upper hoods have a groove and the upper part fits over the lower tray, keeping all liquids IN the litterpan. Taller, open-topped litterboxes made out of Rubbermaid (or other brand
) containers work very well, they simply must have a smooth inside and no support ribs for easy scooping and cleaning of waste.
We also made our own litterbox, but it is HUGE. We call it the LitterChest
, because it looks like a Hope Chest with a cat-flap front entry. The inside is lined with black plexi-glass and caulked at all seams to be water-tight. It is structurally supported underneath to hold the weight of the litter (about 120#
) and on wheels to roll for cleaning loose litter around it. It is also vented outside with clothes-dryer ducting to help control odor and dust.
Some cats just have these pee-habits and in addition to peeing over the edges of the pans, they will sometimes have a strong instinct to bury/hide their waste ... but will scratch everything around
the litterbox - floor, walls, ANYTHING near the l'box - but not the litter itself. We *have* one of these cats and she is the reason we vented the LitterChest outside, so the smell of her deposits wouldn't stink the house if she didn't bury it.
I agree, check and rule out a medical problem if this is a new behavior. If this is just his *usual* behavior then you should only have to change the litterbox and solve the problem that way.
Best of luck, and let us know what you did to solve the problem. The information you share could help others who are having similar problems, too.
