I have two cats and a bunny named Mila. My cats aren't very friendly toward Mila, but they have never tried to hurt her. We live in a townhouse with a small garden. Mila plays outdide the whole day and then I bring her in at night. Yesterday another cat came into our yard and it seems that it is Mila attracting it. I need to keep this cat out of our yard because I think he will hurt Mila but I also have to think about my own cats. Does anyone have any advice for me on keeping this cat out. We do have fence, about 6.5 feet.
