I tried searching the archives but it wasn't all that helpful as my situation with a new kit doesn't fall into line with previous discusions. We had a 3 month old kit transferred to us from the pet store who is costing them money to "fix". No problem and I am glad they think of us. So the male kit has a red irratated penis, specially if you rub the area or his belly. The vet they took him to could only check visually as that is the way funding is set up and suspected a urinary tract infection and prescribed Bactrim every 12 hours. 3ml. The store admits they were not exact on 12 hours but varied from 8-10 hours between first and second dose. He has been on this for 3 weeks. He will see our normal vet this week. No other issues such as color of urine nor feces being irregular. Very active, normal for a 3 month old. No pain - just normal squirmy-ness. I have not delt with this before nor used Bactrim. Any advise would be greatly appreciated. Specially any tests my vet should run that you think would be helpful.
