Updated On September 23rd, 2025

Pet's info: Cat | Bengal | Female | spayed | 7 lbs

My cats been going to the vet for the last month for peeing blood or not peeing. No one could figure the reason after all test but they said they think it's UT with Baterica. They gave her amoxicillin and the last 2 weeks she's been losing hair in random areas rapidly & it's quite concerning. & those are just some of the area and with her moving, I couldn't get too many good shots
