Thanks for all your input. We'll call the vet today and get Cammie in (see if they need a sample first). There must be something wrong because she has 2 cat boxes (one upstairs and one downstairs) that she has always used in the past.

CatDad - Sadly, I'm familiar with kidney problems. Kuhio peed all over the place in the last month of her life. But she was 17. I guess we're still having problems accepting the fact that Cammie is at least 10 years old even though we've just had her since March.

I'll keep you posted.
