Cat Poop

Hello New Friends,
I am an owner of 2 Labs, 1 choc and 1 very large yellow. We have 3 cats, 2 five years old sisters and a 4 years old which was just given to us because of the death of someone we knew. My 1 cat Nala has decided that she is not using a litter box anymore and is pooping on the kid beds. This has been happening on and off since we got the dogs 3 years ago but now its out of control. Please help. I have 3 litter boxes but it's not helping.

Where are the litter boxes located? How often do you scoop? Are the boxes covered or uncovered? You might want to add yet another box (there's a general rule of one per cat, plus one extra), and put it in a different area of the house. There are lots of different reasons for inappropriate elimination in cats, medical being one (constipation, arthritis - not likely in your young cats mind you) and then you need to look at issues like the cleanliness of the boxes, their location (which can be a territorial thing amongst the cats, or maybe a privacy thing, or perhaps a fear thing like if there was a startling noise one time or the dogs disturbed her), and also the type of cat litter. It can also be a way to deal with stress for some cats. These links that might have a few tips for you:

There is also a type of litter or litter additive called Dr. Elsey's Cat Attract (http://www.preciouscat.com/) that can be useful if other changes don't resolve the problem, although it isn't a good substitute for something like a location or cleanliness issue.

Oh, and welcome to pets.ca! Hope you find a solution soon.
