OK, not exactly an impulse buy, but not the best laid out plan I've ever had either. My DD (10) has wanted a mouse for quite some time now. I went to Petco today just to get some info on mice and the clerk told me DD for the most part wouldn't be able to hold and pet the mouse without it trying to get away. She suggested a guinea pig. She had fallen in love with one that has cow licks all over its body so she had been holding it and petting it a lot recently. As she's holding it and talking to me it seems pretty happy so I say I'll take it. The children are not home form school yet and they have no idea! They are going to flip out. What are the odds that she is going to bite and if so does it really hurt.? I'm asking because I want us all to be prepared. Any info you can give my would be great. I think I've got the whole food and shelter thing taken care of but the handling I'm still a little lost on. I've never had any type of animal like this with sharp little teeth.
