[Jane Austen]

Right after I got Duchess I had her loose in the back yard, where she found a chipmunk under some leaves and in a flash had killed it. She also has found mice inside the house and likes to play with them.
In an aside ( I got one of those plug in things that supposed to give off audio frequencies that mice do not like. That seems to keep mice from the kitchen)
I don't let Duchess loose anymore outside my home. She is not reliable with the street nearby. and has gone after dogs people have been walking.
And squirrells also have to be chased up a tree. I encouraged her to chase the squirrells thinking that she would never catch up to them. Now I regret urging her because that just reenforces her carrying it over to stray cats.
As others have said she tolerates our cat but will chase anything that runs. On the rare occasion that she is loose I am afraid she will catch up with the few neighbors cats that sit on our stone walls.
Having her on the leash, we have been working on "Leave It", but I know it won't work if she is loose.
