It's feeding day this week so I'm going to try something different. My 4 year old female who is about 3 and a half feet long is used to getting 4 live adult mice every 2 weeks. That's how her last owner fed her. This week I'm going to try an adult rat. I'm sure she will eat it but my only concern is the rat fighting back. She won't eat F/T so what are the odds of her getting injured by an adult rat?
