Cat owners, help please: Apt being turned into a litter box!

[nancielle]

I'm hoping that some of the cat owners here might be able to help.

I took in an abandoned cat 7 months ago. He's been very good about using the litter box. For the past 1 1/2 weeks he's been peeing on my bedroom door and this morning I found a pee stain on one of my bedroom curtains (one of the windows he likes to hang out in.) For "solids" elimination he uses his box. The box hasn't been moved and it's cleaned very often. He appears healthy (eating/drinking well and very active.) Any thoughts/suggestions would be greatly appreciated.

How often do you change the litterbox?

Even though he's acting fine, still have him checked over. Inappropriate urination can be the first sign of a urinary problem (crystals or infection), otherwise has anything else changed in his life that might be stressing him? Cats usually resort to territory marking if they are feeling encroached upon - new pet, moving etc.

Oh - and he is neutered? If not that can solve a lot of problems.

The litter is 'scooped' several times a day and changed outright every other day.

I forgot to mention that he is neutered. There haven't been any changes in the household routine. He and the dog get along fine (the cat lived in the building before I adopted my dog and they took to each other immediately. They're like velcro.)

Inappropriate urination pattern could mean a urinary infection.
My cat had prolonged vomiting one day and he ended up with a cystitis. When ever my moms cat does a prolonged vomiting, he usually has a kidney stone and they have to usually get him rotor rooted to relieve all that.
By all means, have him checked. My cat aside from an unusual vomiting, was totally normal and playing and running. There's nothing wrong with being an overprotective "mom".

is the pee stain normal color and size? how about the litter box, is the amount you are scooping normal? if it is smaller than normal, that can indicate bladder/urinary tract infection like the others said. if nothing in your life has changed and he's been a normal kitty for 7 months, it is vet time. cats are pretty intelligent and although they can't talk, they can definitely let you know that something isn't right. best of luck to you and the fur baby!

This is a long shot but my Felix (God rest his little kitty soul) would not go pee in the litter box if I used those plastic liners? I don't know why but I found out b/c I ran out of them and just put the litter in strait. Strangely enough he stopped peeing on things?
