There was definitely some type of mite/bug infesting his cage before I treated him with the SCAT. (Which is one of the treatments suggested on Avian.com) The bugs were the size of a pin prick and were particularly thick around his sleeping perch.I had taken him to an avian vet in my area, but she didn't check him for mites and wanted to keep him in an oxygen room and tube feed him. But he was eating just fine when I took him in and I thought the trauma of the suggested treatment would kill him. Also, I couldn't afford the $500 vet stay, especially having spent $250 for the emergency visit. I'll put the vaporizer in his room. And I'll clean his cage and everything in it thoroughly again. Any other suggestions.
Just cleaned cage and everything in it as you directed. AND, dried in the sun. I'll continue to do this every other day for 10 to 15 days. I checked out other avian vets in my area (Boston) and found another who said the initial visit and exam would cost $84.00. Vets are expensive here! I'll watch Limoncello carefully, and if it looks like he's going downhill, I'll bite the bullet and take him in. But I want to try the careful cleaning regime first. I'll let you know how he fares. Thank you for your advise. I hope I'm able to pull him through.
