Oreo is my sweet rat, a feeder rat. I saved her life. But, now she has a tumor the size of a grown man's thumb. Last night, it split the skin. Now, she limps because it drags on the ground, and squeals. Does it hurt her? I think that she is in pain, and feel that it is time to let her go. I am looking for a vet that will euthanize her. But, mom says she doesn't have enough money to get her euthanized and thinks that she is not in pain. She said that if I really think she's in pain, dad can use the pellet gun to put her down! I almost screamed "NO!", I said it so loud! What should I do? We don't have enough money to get her put down? She is suffering and I feel guilty! Help!
