I am hoping you have gotten some word on Pikey's condition by now. If it turns out it is not an intestinal blockage due to a hairball, please ask him about pancreatitis. My big furry boy Stomper went through a similar ordeal as your Pikey - right down to the enema as well. (very indepth thread about it http://www.thecatsite.com/forums/sho...t=pancreatitis
He was finally diagnosised with triaditis w/ chronic pancreatitis, as well as the gallstones which had to be removed. He still has bad episodes and I almost had him euthanized in February, but we got him through it. Management is the key for him. He is doing great now, so you keep your hope up for Pikey. cats are amazingly resilient.
Making sure Pikey eats is of prime importance, especially if he is even a little overweight. ( please note that the vast majority of housecats are overweight. We are used to seeing them this way and think a healthy weight cat is too thin). However if his intestines are blocked assit feeding will only cause him to vomit.
There are medicines which will stimulate appetitie and if Pikey is not blocked then you most certainly should as your vet about them. If he still will not eat then having an E-Tube surgically placed is an option you should consider. I just had one for my Conan, who didn't eat for five days. We were watching his bloodwork and I was giving him daily fluids. Normally I would not let a cat go 5 days, any of my others no way, but Conan is a skinny cat and Hepatic Lipidosis was not as much of a worry as what else was going on.
E-tubes are easy and cats adapt to them very quickly.
An interesting note, you can force feed a starved cat too much too quickly. My vet said to feed Conan only 1/3 of a can of food a day for 3 days. Cats can get on overfeeding syndrome which causes I think a phosporus...maybe potassium (can remember which) spike which can be deadly. This was the first I had heard of this and I am pretty on top of things. If they start eating on their own, this won't happen, only with assisted feeding. Something I meant to look up the research on and haven't yet.
Sending lots of
vibes that Pikey just needed an enema and that he is on the mend now.
