I have three adult cats; my one girl, Chaney, although a purebred Devon Rex from a breeder, was pretty much feral when I got her. The breeder has no clue what triggered her wild behaviour by the way. Chaney decided that she liked our piano room to poo and pee
. Been to the vet, tried changing diets ... no luck. I finally put a litter box in the exact spot that she was using and voila, she used the litter box. Then I tried to ever so slowly move the litter box out of the room ... a few inches at a time. Nope, she went back to her old spot
. She's also peed on the couch (just once, mind you) and when my husband tried to grab her, she bit him.
We now have a litter box in the piano room ... indefinitely. She's only missed a couple of times in the past 2 weeks. I firmly believe in not punishing my cats. If she poos somewhere she is not supposed to, I don't grab her, spray her with water, hit her, push her face in it or otherwise. If I catch her in the act, I try to remain calm, place her in the litter box and tell her what a naughty cat she is. If I don't catch her in the act, I simply clean it up and make sure there is no trace of scent left on the spot. It can be very frustrating to get a cat to use a litter box once they've decided that the floor/couch/bed is more convenient for them.
By the way, her personality has improved considerably with lots of TLC - even stopped hissing at my hubby
The recently had a litter of Devon Rex kittens that have no hint of their Mom's crazy personality either
