Question

One of my six cats, Tuffy, seems to have a bowel problem. He is over 15 yrs old so I'm not leaning toward sugery. He strains to go and his feces are thin and wormlike. Sometimes diarhea. Subsequently he is now refusing to use the litter boxes which are kept very clean. He goes to the basement and does his business on the landing where we now spread newspaper. We've tried different types of litter and putting a box on the landing to no avail. He is on prednisone and tylan to control the inflamation and diarhea. A big problem for him is gas. Is there anything we can give him to control this as it seems to cause Tuffy great discomfort? Tuffy is a great pet who has seen his fair share of troubles. Eight years ago he suffered from encephalitis. We were told to put him down. We decided to hang in there and had to reteach him how to eat, drink, and evacuate. Very time consuming but, worth the effort. Any insight or advice will be appreciated. Thank you. Cherie
