Pets I believe. But they take off as soon as I get outside so I can't see if they have collars or not. I mean besides fencing, sometimes I want something to make them realize not to get on my property.

They haven't been by most of this week but we do make sure that all the cats are in by the time I go to bed. Especially since the dogs haven't been by the cats are wanting to go outside more. It's getting colder out and they love that. :>
