My cat recently had a urethral blockage. He spent several days at the 24 hour vet. Since coming home he is now peeing everywhere he walks. He is not using the litter box at all. The vet said that this could be due to stretching and his bladder/urethral area may shrink back. Has anyone had this and if so how long until we will start to see signs of improvement. It has been like this for 5 days now with no improvements and the peeing is getting worse.
