I'm glad you're checking back with the vet today. A few weeks ago when Tubby had his bladder infection, I realized there was a problem because he, too, was just sitting in the litter box - which he had never done before. I took him to the vet first thing in the morning, and gave him his first antibiotic pill when we got back home - about 9:30 am or so. By the time I got home that evening I could already tell he was getting better. He was not licking himself anymore (like Ritzy is licking) and he was slepping well instead of wandering back and forth between the litter boxes and trying to pee. By the time I got home the second day, he was pretty much back to normal. He was still peeing less and more frequently, but he was acting completely normal - down to the dinnertime begging routine.

So now that it's day 5 for Ritzy, I would definitely be worried that she hasn't shown more sign of improvement. I don't remember the name of the antibiotic Tubby was on, but I can call and ask them if you would like.

I've heard that cats lick when they are in pain, which would explain why she's licking herself more, but as much as I hate to say it, it's possible this is more than just a bladder infection if it hasn't started clearing up by now. Maybe she just needs a different kind of antibiotic.

I'm absolutely, positively praying and sending positive thoughts for dear Ritzy. She - and we all here at PT - really need her to get well!
