Yeah that's what I was cautioned about - the scratching of her insides as they go down - these were very tiny mice so I knew it might not be that big of a deal....but I like to be very careful. I have seen lots of people's pets die/get hurt because they were careless and I don't want to be in that boat. She got the first one down, she just killed the second little guy. Thanks for putting my mind at ease guys![]()
