My cat Coco (female three years old) has blood in Urine. After bringing her to the vet and having a Urine analysis done, the vet decided to give her antibiotics. He mentioned that they could see a bacterial infection and thought it was coming from the liver. After treating her with a round of antibiotics for 15 days, the quantity of blood in Urine was lower but unfortunately still there. He switches the antibiotics to amoxicillin and treats her for 7 days. It went a lot better but still blood in the urine and Coco was developing a fever at this time. Blood analysis came back alright with no specific sign except an infection showing. So the vet changed the antibiotic and used on for the kidney this time. He mentioned that if nothing gets better then, it might be a pancreas infection and as our cat is obese (very tall cat 16.7 pounds), the kidneys are suffering and gorging or are inflamed from the pancreas and it might be why she is bleeding. We were giving kibble to my cat and for now a full month, she is eating only one can of food a day (a small can of Nulo). He told us to continue the third antibiotic (Baytril)and if at the end of the 10 days, she still bleeds, we should treat the pancreas with some other tablets and do eventually an ultrasound to see where we are staying at. I am getting worried for my cat as she is developing a fever, starting to sleep more, and searching for comfort, pee still blood, and even more as when we brought her the first time! She is not dehydrated, she drinks normally and pees a lot, with no blockage. She is going to her litter multiple times (too often for sure) and does not seem to be in pain. She strangely loves to go into our bath tub now and lays there. My worries and my question is how long can a cat keeps going on like that with rounds of different antibiotic and not getting better? Should I consult another vet for a double opinion?
