Forgive me for the late response as I've been away for a few days and just got back this afternoon.

Welcome to Pet Talk. Along with Debbie (T & P's Mom) I've had alot of experience with UTI's and believe me it's nothing to fool around with. When I first got Speckles she had recurring UTI's for the first year. It seemed that we would put her on meds and when they did not work the vet would change it to something else. This went on and on until finally he did a "sensitivity test" and found that the infection would most likely respond to Sulphatrim (spelling?) and that's the meds that she was given for all other UTI's.

It is very common for the vet to hand out those crystals for kitty to pee in. I had to do that earlier this year with my male cat, Max. I'm sure you will get the results back in a day and I'm glad that she's on antibiotics now.

What is your kitty's name?
