I am sorry Gary. It could be Tubster, as no matter how well fed they are, they still like to dig in trash, I take it that they get excited in the forging efforts

The only way to know for sure is to keep him completely indoors for awhile, and see it they still complain.

If they complain to AC, could they take the other cats from you? I hope not.

Anyways, the only thing you can do to keep him indoors, is just to do it cold turkey. BUT you must have the patience of a saint... He will not be happy, and will beg and scream and try everything to get you to cave. Probably even keep you up all night long. I did it successfully with about 7 of my cats ( they were strays and probably born outside as well) and with PLENTY of fosters. It just takes some time.... But now mine dont even WANT to go outdoors. It is like they accepted it and moved on.

GOOD LUCK! And keep us posted!
