I just got back fron the vet. I had fecal screens done on my snakes Monday and they came back positive for pinworms. Today I took them all in to have weighed for meds. They were weighed and treated with Panacure, and I am to give them another dose in 2 weeks. I get home and one of my snakes was looking terrible, not moving with his mouth agape. I put his head in the water dish and he couldn't pull his head out, so I laid his head back down in his tub. I've been watching him just lay there and now I think he's dead. If he's breathing it's so shallow I can't visually see it. I'm about to go check on him again. Anyone have any ideas? Could he possibly be allergic to Panacure. I don't think he was overdosed, all the other snakes look fine. The vets office is closed. Going to check on him again. This is very bad.
