Our kitty has suffered with bowel issues for years until I stumbled in this web site -
https://littlebigcat.com/constipated-cats/ . Now he gets 1/4 tsp of Restoralax (or generic substitute) twice a day, mixed with a 1/2 small can of cat food. Also the vet has him on special high fibre dry cat food. Also we discovered that making water more attractive to drink by getting him a water fountain (located far away from his feeding area). It was a real eye opener to see how often he was at it when before he drank very little water. Hope some of this helps you.
