Desperate help needed

[ericmtl]

My cat is around 4 years old and suffers from chronic constipation. He is presently at the vet and my last resort is a colascopy. I need to know if it is worth it. What are the side effects besides diarrhea. I so don't want to have my little baby euthanized. I have been crying for the past 4 days and cannot see myself living without my cat. The vet tried to removed its feces from the colon but wasn't entirely successful. I don't care if my cat sh!ts on the floor, on my bed or me, it can always be cleaned. I want my baby to have a good quality life. I want to hear from owners who have gone through the same thing. I only have a few days left. Yuki, that is my cat's name, is the best thing that has ever happened in my life. I've rescued him and want the best life possible for this God sent gift. Please send feedback. Thank you.
