SJ has killed mouses in the houses last winter. I think she was disappointed when they stopped squeaking. She has a high prey drive and I fear that she is going to launch herself right off the back of the couch (d/b/a designated patrol tower) through the plate glass window one of these days.
She whines and whimpers and squeals to get at the squirrels and rabbits in the yard something awful. Gets the shakes. I pity the bunny if she ever catches one.
