So Ronnie is still peeing outside of his litterbox. Sigh. He does great for a few days and then slips.
From what I can tell, I might have too much litter in his litter box, so I emptied it down to just about an inch to an inch and a half deep. I also added a liberal amount of baking soda to help neutralize any odor. Then I mopped the floor he tends to use the most and moved the box over it.
Now, he is going to spend most of his time locked in the bathroom with his food and water bowls and his litter box. It's not my first choice, by any means, but Mr. Gaia is really fed up. I'm going to give him liberal praise every time I hear him scratch in his box and will put him in his box and praise him while he's there.
I did switch litters and it helped for a time, so I'll stick with it for now.
