Please take him and the part you cut off. If it has to be, it would be better to put him to sleep than let him die a long and painful death.
Take him to a vet if they really can't do anything than he will at least be euthanized humanely. Feel horrible for the baby and I really hate vets like that.Is there any hope if I went to another vet or I'll only be torturing him ?
I'm really trying to figure that out myself, I hate to always be doubting the vet, since he saw it in person, but still, can't imagine how he could live through this.
I really rather not break it to you, but if you tied something intestine wise off, then cut it, it's not going to end will for the kitty. How on earth does any Vet think this little one will be able to pass waste or anything at all for that matter. I strongly suggest you have this little one put down. I'm not one to give up on them, not at all but I can't imagine the pain he must be going through. Are you in the US by any chance? If cost if a factor, perhaps if you explained what is wrong with him they would help you somehow for his sake.
I can only figure that the other end that once it was cut is already either bleeding or dying inside him. Again, I'm very sorry.
