We are trying to feed her small mice 20 grams and under, because she was so intimidated but the rat pups the breeder had her on. She is in a 20 gallon tank and has a log that runs the length of the tank and the two hides, which aren't really snug on her but they aren't to much bigger than her, but that is definitely something we can change. We have tried leaving food close to her but she just ignores it and we take it out late the next day. We have never done freshly killed but we will give it a shot if she doesn't go for live. What are the best/ most humane ways to kill a mouse? Thanks so much!!
