He tends to be skittish especially around people he doesn't know, but every morning he is at the front door looking for his breakfast.
We don't know where he came from, but we used to see him around several years ago when our cats were still alive. Lately we have been seeing a small fluffy gray haired cat hanging around. I think it realizes that Rusty is getting older and it is getting bolder.
If it ever warms up to us as Rusty has I should be able to catch it napping also.
