Hi, I'm Gavin's owner; Gavin's the first Piggy I've ever had and it was a spontaneous decision to get him, so not much research was done. I've had him for about 4-5 years now and about a week ago I noticed he stopped eating, drinking, peeing, pooping, and moving other than to reposition himself before going back to sleep. I took him to a local vet and they couldn't find anything wrong except a sore that was beginning to form in his mouth but she said it shouldn't have been causing that yet. She said it may be a blockage of poop because the anus muscles can grow weak in age, can't think of the technical term at the moment, she gave us a antibiotic, something to help give him an appetite, and another one I can't remember what it was for at the moment. She also gave us Critical Care. At first he was able to take it all decently. But as the week went by he slowly started to gag on the CC. Now every time we give him some he makes a noise like he wants to throw it up. We tried veggies and noticed he'll eat some, though he'll still gag, but other than that we've stopped feeding him the CC out of fear of accidentally killing him while trying to feed him and that none of it even goes in his mouth most of the time from him moving, not allowing us to get the tip in the side of his mouth. As of a day or so ago he's more active (gives us fuss for picking him up like he use to and will sometimes run around the cage and flip his hay ball) and he'll go seeking for water when he's thirsty. He still won't eat anything unless we put a spinach leaf at the opening of his mouth for him to eat. I don't know what to do, I don't want to put him to sleep and realise he could've been cured. Someone please help.
