I have never dealt with an RI but I know when I was healing a burn on a rescue we had it took forever the Vet explained it to me this way. Reptile have very slow metabolisms and take a lot longer to heal and show signs of improvement so I would hold off until Monday and see what the Vet has to say. Maybe someone with some RI experience will chime in but I thought I would at least give my history with reptiles and healing.
