Bart has recently gone on a spree of ... shall we say, thinking outside the litterbox.
I tried the carpet cleaner on it a week or so ago, and it ultimately seemed to kick up yet more stink. Put Simple Solution on it... it didnt' seem to help much. I finally tried putting mothballs around the area to keep him from lingering there, but they smelled nearly as bad as the pee -- actually seemed to enhance the smell through some sort of odor-synergy, making it worse.
We started locking Bart in the bathroom with his food and water and the litterbox access behind the toilet (a hole to get to the furnace area under the stairs). Oddly, he didn't seem to mind as much as we thought -- he'd voluntarily go in there at various times of day to sit in the laundry basket with the blanket in it we'd set up for him.
I got on the web and found this stuff -- chemical, not enzyme -- called "odorcide" that professionals use to clean up "dead man" smell and other organic odors. The concentrate is something like $90 a gallon (but you can make 16 gallons with that). I found some at Red Hot Carpet Cleaners that came in a 16 oz package -- enough to make 2 gallons. I hung my hopes on that.
In the mean time, night before last when I got home, I heard a hissing sound coming from under the kitchen sink. It was wet. I felt around for where the leak was coming from -- apparently our water filter cracked. I had no idea how long it had been leaking, but the kitchen rug was wet. So after I got the water to the filter shut off, I went downstairs and found water in the room underneath the kitchen in the basement. Some in the ceiling, a lot in the rug in front of the closet and running over toward the furnace room. And a strong cat pee odor. Apparently he'd been doing it in there, too, and the moisture kicked it up. I spent most of the evening sucking about 5 gallons of water out of the carpet down there with the carpet cleaner.
The Odorcide came yesterday. Well, now I know why nursing homes smell like they do. I'm guessing they use this stuff. It's supposed to be some sort of spice smell, I can tell, with some gingery smell. I wish they'd just left the fragrance out of it. Unless that fragrance actually has something to do with how the fats and salts get broken down. And that's what it's supposed to do -- break down the oils and salts that other products don't.
I must say I'm not terribly pleased with the smell. I've used about half of it, and I'm wating for it to dry. We have fans and the dehumidifier going.
I got a brighter light for the litterbox area -- we're letting him roam free again and I'm hoping the week he spent in the laundry room has re-trained him that the litterbox is the place to go. It needs to be as inviting as possible, and the "preferred" places outside of the litterbox need to be made as un-inviting as possible. The CatScrams seem to work for the most part, but frankly I probably need a couple more of them.
Part of the problem is he needs to go through the area we're trying to protect to get to the litterbox. And no, we're not moving the litterbox. It's pretty much in the only place we're willing to put one. And he even used to pee right next to it -- so it's not that he didn't like going in there at all.
If this doesn't work -- I'm afraid Bart is going to have to make a premature exit from the world. I hate to do it, but I don't want to live in a cat pee home.
