HELP! I HAVE A MEGACOLON CAT

I NEED HELP FROM THIS FORUM - I rescued a small cat about 4 months ago. He had severe magne. He is better now but I noticed about 1 months ago that he was not using the litterbox. I rushed him to the local vet and they put him to sleep and gave him several enemas and helped manually push out his stool and for that they charged me $900.00!  They gave me cridprise and laxatuse liquids and put him on a Science Diet prescription food W/D. Eight days later he had not moved his bowels, back I went and they did the same and charged me $711!  I am new at this and asked the Vet Tech to show me how to give him an enema and she did, however I brought her the Children's enema and was told that One would be good for 10 applications.  I have given him 2 small squeezes of the bottle and NOTHING!  I have tried to get him to eat pumpkin but no success and when he did just some small runny stool.

I need to know what kind of enemas that people out in the cat community are using and how much and how often. Some people are telling me to put him down. That goes against everything I stand for and believe in. This little guy has had a tough beginning of his life, and I'm not going to give up on him because he can't poo.  I volunteer every weekend for a local animal rescue group here in Upland, California and spent my entire time other than work, rescuing animals - mostly from the local shelter and other situations, like Charley who came to my bedroom window.  

I am running out of funds and still need answers. Oh, the Dr. has Charley on Zantac, it is suppose help, but I have not seen anything.

So........that being said can anyone out there HELP ME.  I know he is miserable.  I foster other cats and have a couple of my own and Charley is picking a fight with all of them.

Thanks to everyone for their assistance.

I hate vets that take advantage of people please do not go back to the same vet they do not deserve you as a customer and they could be doing you kitty a lot of harm. After all that money you should have a clear answer as to why and how you can prevent it from happening again if you don't ring them up and demand answers and if you have to take him back say you want it fixed this time as obviously they didn't do what they charged you for ...fix your cat.
Susan, what goes in the front end comes out the back and unless you cat is diagnosed with a section of the bowl that is damaged and cannot push the poop along you should be able to rectifiy this.
Do not feed you cat biscuits they will only bind and can make things worse. You should be feeding your cat food that has gavy's and you should mix a little water  with it to make the stools soft and again you can add a fish oil capusle each day to add a lubricant. I have a number of cats come to stay who have toilet problems of this nature and we can usually get it under control. If you go back to your vet get them to show you how to check if their is poop that is hard in the bowl and getting clogged because if you can do this then you can always give them a little lubricant medication to move it before it becomes compacted.
All the best with your kitten we rescue about 140 a year here including wet nursing from one week old so know how you are feeling.
