Cat Pee in Bed!

Question
After waking up to cat pee in our bed a couple of times recently, we took all three of our cats to the vet who checked each for bladder infection but didn't find any. Instead, we discovered the oldest of our cats now has a significant amount of blood in her urine as her kidneys are apparently failing. Our hypothesis, then, is that she may be leaking small amounts of urine (containing blood and whatever else) which is unduely encouraging the dominant male cat in our household to place his significant mark over. Does that sound like a reasonable theory for the sudden peeing in bed? Or do you think we should be looking elsewhere? We don't think any of our cats is purposely acting badly but something strange is going on. For the moment, we've isolated the dominant male in one part of our condo, away from the ailing female and master bedroom to see if that reveals anything new (and to emphasize to him that peeing in our bed is not acceptable). While I'm not totally convinced he's doing most/all of the peeing, it's likely he is from what we've actually seen (since we've been asleep when most of the peeing in bed occurred). My wife and I, married now about a year and a half, only merged our cats--two of which were mine (including the dominant male) while the ailing 13-year-old female was hers--temporarily in her condo (while we plan for a house) about 15 months ago, and while they haven't become the best of friends they have lived somewhat amicably for a good part of that time. Also, while the male used to be an indoor/outdoor cat, since moving to my wife's condo, he's been confined indoors. Any insights you can provide on how we can improve our present situation (and possibly solve this problem) would be greatly appreciated. Thanks!

Hi Evan,

Yes, you do have a difficult situation.  If your older female is in kidney failure, then what you are describing is quite normal. I went through the exact same thing.  My cat was 17 yrs old and I loved her dearly, so I bought a cheap shower curtain and put in over the bed where she normally slept and put an old blanket on top of it.  It conatained the problem, but of course she didn't get any better and I ended up putting her to sleep, which was the kindest thing I could do at the time.  She had lost weight and was looking really sad.  Your male cat is most likely doing exactly as you  have said. He is marking the area, which is very normal for male cats.  (and why I don't ever want another male cat! lol).   I really don't know what to tell you, I doubt you will be able to control him any other way than what you are doing now.  You don't want him to mark after her and get used to it.   Then you may never stop him.   If it is possible to keep him confined from her unless you can watch them closely, that's what I would do..... especially at night.

I'm glad to know that you are concerned enough to try and help them , rather than throw them outside like a lot of people do.  That tells me you are responsible pet owners, not to mention that you obviously love your cats!

Good Luck,
Becky
