Be vewy vewy quiet, I'm hunting wabbits

A few days ago 4 rabbits just appeared in the yard. I've only been able to capture picture of 3 of the 4. As you can see they are not your typical 'wild' rabbits. Looks like someone has decided they no longer want their pets anymore. Now we feed them and they entertain us. They remind me of several of the cats Christy and I had when we were younger.
