Over the years, my wife and I have slowly added pets to the house.
Shortly after Mini-Dex#1 was born we got our first cat, Sammy. She is essentially my cat. She doesn't really like anyone except me. She sleeps on my side of the bed, pretty much only lets me pet her (although she is better as she's gotten older), and she curls up in my lap when watching TV.
Then about the time Mini-Dex #2 came along, we got our 2nd cat, Sophie. We figured it would be easier to teach Mini-Dex #1 (who wasn't even 2 at the time) how to be gentile with a kitten as opposed to his sister.
Everyone got along great. No problems as long as the litterbox was cleaned regularly, although as the kids got older we would find a pile of cat poo in a corner (typically because the litterbox was overdue for a cleaning). Then we moved to a new rental house where the previous renters had a cat that had marked all over the basement. No matter how much we tried to clean it up, my cats would continue to re-mark the spots. Only way to get them to stop was to literally put a piece of furniture in front of/on top of the spot. Let's just say we lost the deposit on that house...
Then we moved to the new house. We figured there would be no more problems with the cats peeing all over the place because it was a "clean slate". And we were right. Until we got Jax, our dog. Then the cats began peeing all over the basement. If something was on the floor, they peed on it. Additionally, if any of us went down to the basement and spent more than 30 minutes down there (for whatever reason), the cats would not come down there and consequently piss on something upstairs. We have probably two-dozen cat piss stains on the basement floor now (bare concrete). So we decided to move the litterbox out of the basement and close that part of the house off so they weren't peeing there anymore. Shortly before Xmas, one of the cats pissed on our brand new comforter ($300 straight into the trashcan). RIght in the place they normally sleep. We were lucky the comforter soaked it up because we had just bought a new $2000 mattress...
The whole time, we were noticing that the litterbox was still being used. It was cleaned regularly, so we started assuming it was only one of the cats, Sophie. In the meantime, we would start to wake up to random "poop trails" in the house. Not the typical pile in the corner, but instead we would find 5-6 turds starting at the top of the stairs and continue down the stairs, across the living room, into the kitchen, etc. We keep the dogs in the garage overnight, so this isn't a case of the dogs dragging this across the house, but rather a case of the "running poops" by one of the cats. And these aren't regular turds either. They're typically dried up, very dense, and look like they're a week old. We finally caught Sophie doing it one afternoon. Looks like she has some form of gastro-intestinal problem that is causing her to get constipated. No clue on how to treat that, and a google search says it could be anything from being dehydrated to some very serious colon problems.
Now add our 2nd dog, Zeus. Between the two dogs, it is now a race to see which one can get the "tootsie rolls" out of the litterbox faster. Because the dogs are constanly scanning the litterbox, it appears Sophie won't use it anymore. Even if the dogs are outside or in the garage overnight. She actually walked into the office yesterday afternoon and pissed on a pile of papers next to the desk, right next to me. Needless to say, she got her ass whooped. She was also locked into the laundry room overnight (where the litterbox & food/water are located). When I checked on her this morning, she had pissed on the floor, not in the litterbox only 2 feet away.
I am at a loss as to what to do with the cat. I don't necessarily want to get rid of her, but that seems to be the only logical thing to do because her problems only escalated as more people/pets were in the mix. I'm thinking if she can be in a one-pet home, she would be much better off...
