Have recently set up a new run and hen house. Now mice have moved in. I'm thinking of getting two young cats and having them live in the run with the chickens. The cats would have their own cat house and be well looked after. The run is large, 25 by 20 feet. Is this a bad idea? Would the kittens/cats hunt the hens or would the hens hurt the kittens? I have an image of a barn yard cat working for a living. I already have adopted a 3 mounth old kitten and will pick her up on monday. Only problem is she is too cute and will probably end up a spoiled indoor lap cat.
