Sadly, I am going in-bed now a-ha-ha-ha as it's very late here and old people need their sleep otherwise their gums shrink even more and their dentures fall out.
Eeeep no! Cats on beds are bad for you. They sit on your face and smother you. Or draw out your life-force with their evil succubus-like devilry.
At the very least, they cover your duvet in furball vomit and catscuzz.
Now, weasels on the other hand ..... ah, but to bed I go. Sayonara :-)
