Since the winter has been setting in I noticed a burst in the field mice population inside the house. So I invested in 2 small so called mouser bloodline kittens. We would often joke about how we couldn't wait till there bigger as we watch a mouse scamper by.This morning I heard this God aweful squeeeeeeek. and this is what I found. I raised these cats with my chicks in the brooder so there definatly chicken friendly.
