Thanks again! It is a small patch about the size of a dime. I am on my way to get a new hide and some mice. I wish I could find the african rats again, I hate feeding rats-- I like them too much. I know I could use frozen ones, but I still like the rat that was killed. As long as I feed 2-3 mice at a time is that OK? I put in one at a time and watch so it does not hurt Monty. Someone once mentioned to me that you had to feed large enough prey to stretch their jaws?
