Well, the Bart problem isn't getting any better. I put a rubber runner down over the weekend, and he's just taken to "going" on that. At least it doesn't get in the carpet, but that's not the point. He was supposed to look at it and go "oh, that's not absorbant. I know a better place (hint: how about the litterbox?)"
So last night, I put a mild bleach solution in the carpet cleaner and went over the whole carpet area, and put some fans on it to dry it out. I know. "You'll ruin the carpet." As if the cat pee hasn't already.
It did a pretty good job except for in his favorite spot, which I saturated with enzyme this morning.
Bart spent the night in prision last night. Hey, it's better than a shotgun, which is moving up on my list of solutions. We closed him up in the laundry room where he has access to his food and water and to the litterbox area under the stairs. Got his old basket down from the attic and put a towel in it with a light sprinkling of catnip.
He was meowing loudly this morning. I let him out for about an hour -- watching him carefully. Then I locked him back up. He's going to spend the next several days this way. He's already meowing again. Tough. The alternative is lead to the head, buddy, take your pick.
He might even get exiled to Brian's house for at least a short time period. Even if Brian will take him over the weekend.
He's got to get out of the habit, and I have to eliminate the smells from his "adopted" litter area. I'll also change his litter to something less scented. That might be a part of the problem as well.
