So Bandit just cant catch a break, I thought he was sick again last night from eating the wrong food..nope! Turns out his urinary tract is blocked and he cant empty his bladder. His bladder is sitting hard and full, this can cause kidney damage after as little as 24 hours. Needless to say I am in a state, I took him to the vet first thing and she said this is an "Emergency condition", I didn't even have time to think before she whisked him away to get a catheter in to try and remove the fluid build up. Has anyone got a male cat who has had this condition before? Does anyone have any tips on how to prevent re-occurance of this condition in the future? I already have him on a specialized diet, and he drinks only filtered water. I mix extra water into his food.
