That first picture cracked me up! It looks like the cat thinks the sewing foot is a mouse. See his tail .. all ruffled up.
I am glad you claimed the cat's room as your own. They don't seem to mind at all...LoL! This must make you extremely happy to have your sewing where you can walk out and leave it. I remember what it was like to have to straighten up so dinner could be served, or company coming over, or whatever!
Congratulations on your new place to sew. I am sure you love it!
