SIGNS, excellent thanks so much Phred and everyone else who said that.

Due to the electrical work, every room in the house and also the cellar are going to involved at some time or other.

I already made sure I have collars and ID tags for everyone, too.

Realized last night (as I was down there for this purpose) that the cellar is currently not cat friendly. I've been selling furniture and all the odds and ends have been piled up down there. No second floor, thanks for that thought as well.

The "stuff" in the cellar needs to be packed for the church yard sale next Spring, so it isn't going anywhere soon.

This is all very helpful, thanks everyone!
