I feel on one of my older rats(about 16 months old) that she may have a tumor on her side. Its about the size of a ping pong ball. I was planning on keeping her until she dies naturally since she was my favorite rat but not now. Is it safe to humanely euthanize her and feed her to a snake? I am just worried that the tumor like growth may pass something on to the snake. I'm not asking what you feel is morally correct to do with a "pet status" feeder but rather if it is safe to do or not.
