Ok so like Neosporin? Or where can you buy silvadene cream? Thanks for your help.That is either a burn or bumble foot. Burns can occur when they get too close to a basking light for too long. Bumble foot comes from standing on the same sized branches constantly. I would start with first aid of triple antibiotic ointment or silvadene cream now. Then look into having him/her seen by a vet. Then readjust your cage as needed.
Ok and yes we have a vet we take her to.Yes Neosporin the other is silver sulfadiazine burn cream you may be able to get it at the pharmacy or from your vet.
Do you have a reptile vet?
