Also many bulbs are filled with inert gases rather than being vacuums.
I’ve got a cat (indoor only) who’s normally a lovely little guy who love pets and cuddles. The occasions he slips outside he becomes a rage monster and it often involves getting mauled to catch him and get him back inside.
Being outside their normal space can make cats anxious, anxiety makes affection unwanted. She’s concerned her idiot humans will get hurt/lost and she’s being vigilant for threats.
