After returning from 2 and a half weeks holidays I noticed my brown tree snake had a kink or lump in its back. It pokes out on a weird angle and he cant move properly with it. His eating fine and pooing, the vet gave us some antibiotics which we have been injecting each day. The scans are quite pricey so Xray isnt really an option. i will try and post photos soon - hopefully. we got back on the 16th Jan so he seems fine, just the lump seems a little bigger.
