...I 

osted this in Kitty Central as well, but figured I'd try here too...
Our cat, Kleio, has had an umbilical hernia since we first adopted her at 8 weeks. She was supposed to have this repaired when she went in for her spay (this was through a spay/neuter program through the shelter we adopted her at, so we didn't have to pay for the procedure). Well, the veterinarian did not repair her hernia, and when I inquired as to why, I was told that the vet didn't think it posed a problem, and didn't see it necessary to repair.
It is a rather small hernia. It protrudes about 3/4" on her belly, and is about 3/4" in diameter. It has not grown at all since she's reached maturity, and it doesn't seem to bother her at all.
We asked our regular vet about it at Kleio's last appointment (this same vet has seen her since she was a kitten and has been aware of the hernia), and she told us that although the chances are very slim, that Kleio could develop complications later in life as a result of the hernia (possible intestinal blockage due to hernia growth). The vet told us that we would be wise to have this repaired eventually, just in case.
What do you all recommend?? Have any of you dealt with this in any or your cats, and if so, what was your course of action? We certainly don't mind having the surgery done if it is necessary, but I'd really rather not put Kleio through an unnecessary surgery if at all possible. Thanks!!
