My cat is 22 years old, and for the past year, he's been peeing out through the door of his box. We have one of the boxes with a top cover. This started when I turned his box 90 degrees to fit better in our bathroom and it only happened occasionally. I read somewhere that cat's develop preference for a corner of the box to go in, so turning the box confused him. But by the time I read that and turned the box back, it was too late and just confused him more. Nothing's helped... I tried getting a bigger box, a box with one of the swinging doors (he just hangs his bum out with the door tilted open), and cleaning the box more often. Over the past year he's started to go more and more out the door, and now he's probably doing it 75% of the time.
I need some new ideas. I'm pregnant and my sweet husband has been put in charge of the cat box, and it's driving him crazy to have to deal with pee on the floor multiple times a day. He's the sweetest snuggliest cat, and he goes into the box every time, so I know he still wants and tries to use the box, but he is getting old and I don't know what to do to retrain him or how to modify the box to make it work. Any ideas would be so appreciated!
