I remember the symptoms better than the treatment..
I found Elliott lying on the floor of his cage struggling to breathe, I thought he was having a respiratory attack and after I got him to calm down enough I gave him a dose of Baytril. I sat up with him for most of the night. He was so weak I though there was no way he'd make it to morning. He also had loose stools, but I wouldn't call it diahorea.
I got him into the vet at 8.30 am the next morning, the vet felt his abdomen and you could hear the air popping around inside him. He said the breathing difficulty was because he was so full of air that it was pushing on his lungs.
He took a poo sample which he analysed and said there were Coccidia eggs present, though there were also other worms there. He said to stay on the course of Baytril to rule out any infection and to dose him with Ivermectin oral.
Maybe he just didn't get a bad strain of it like Marigold as this treatment worked and Elliott is now a big healthy boy.(I didn't have the couple of hundred dollars to figure out which Coccidia it was).
