Thank yo soooooo much for the heads up!
Sounds as if he will stay in the downstairs half of the house till he is settled a bit!
We have screened porches on either door there, the upstairs entrance door doesn't!! So he will be a downstairs kitty for a while
Io never goes up stairs unless we carry him, as he doesn't like the narrow stairwell So Jupiter will always have at least one brother to play with!
The rest of the kitties go up and down depending on the sunbeams LOL
