I'm sorry to hear that Bobo has a UTI but in about 2-3 days he should be feeling much better. Storm's had a few of these and they can be very painful but they clear up quickly.

A good thing to do in the future is to make sure that Bobo drinks a lot of water. If you already feed him wet food then you should also add a little bit of water to this to add even more moisture. I hope he feels better soon.
