Blocked Cat Cannot Urinate after catheter treatment. Brought our boy (age 6) to the vet Friday 9/13/19 He was totally blocked. Vet did catheter and IV overnight. Showed great improvement. Still a bit slow to urinate but peed beautifully (on the toilet bowl–yes he often does this). Vet wanted to keep him for observation while we were at work, but again his urination was only dribbles. He’s back at the vet for 2nd night of overnight catheter again. Any insight?? Vet is saying the slow urine stream/lack of urine is due to inflammation. Then how did he pee so beautifully on Wednesday? Very confused, frustrated, and want our baby back home! Any help or insight would be greatly appreciated Thanks.
