Looking for help with a rescued male cat (Smiley) suffering with consitpation for over a year now. Have been treating him with Enulose, Propulsid for over a year now with no improvement. The vet put him on Prescription Hills R/D dry food and also still adding fiber to his can food. Since then he's been in for enemas January 2, February 13 and March 13. I'm looking to try the opposite of less fiber. Before this began we had him on no grain dry food and fancy feast can food. Will not eat the healthy can food. Has anyone used the Miralax along with the Propulsid and Enulose at the start. Thanks for any suggestions..
