agreed. Get the cat checked for infection.

My cats let me know in not so pleasent ways when they think they're litter box is dirty, so it could be that too. I have two boxes, since my tiger kitty is very territorial. (two bowls, two boxes - just so the other one isn't attacked everytime she tries to do something )

I made some reminders in my computer calander to check up on their stuff so they don't have to resort to telling me the hard way that I've been slacking.
