Dad!!!! Theres a Mouse in the Bunny Barn!!!!!!!

So one day Jensen and I went out to feed the bunny's. We heard a scratch and a squeak . Jensen and I immediately started freaking out. We thought it was a bird. Then, Jensen saw a little black head come out from the insulation. We ran into the house screaming Dad!!!!! There's a mouse!!!!! Later dad and mom told us to go clean the barn so we did. Jensen told me to take the nesting box out so we could sweep the floor. I thought the mouse could possibly be in there so I scooted it out with the broom and as soon as the box moved, the mouse jumped out and scurried away. Jensen and I ran away screaming, " Dad!!! Dad!! We saw the mouse." We are getting some poison from the store but we are still scared to go out to feed our animals.
