Hello my tangerine leopard gecko has tumor growth all over her body, I took her to the vets and they said there's not much they can do other than medication for the discomfort. The tumors are not getting any better and they are even spreading, there is one on the back of her eyes that made her go blind in one eye, she needs special care now as she struggles to catch her food. Anything else I can do for her? at what point would euthanasia be necessary?
