I have a red footed tortoise, I have no idea how old she is, I have had her since October. She has pneumonia and has been on antibiotics, she doesn’t seem like she is getting better. I am a new tortoise owner, she is my first one and I feel like I am failing! She is in a wooden tortoise box, should I switch her to a plastic bin? Will that maintain the humidity and heat better? Any advice is welcome.
