I’ve got a theory about cats stealing babies breaths.
Babies drink milk. Kitties love milk. Babies breaths smells like milk. Kitties try to find the source of the milky smell, they put their noses (and whole heads) into kitties mouths.
I had a very curious kitty sleeping on my chest once while I was reading before going to sleep. I yawned and she stuck he whole head in my mouth. It was cute, but I can imagine that a baby has a smaller mouth than me and a kitty’s head could certainly block her airway and suffocate her.
Ah, but cats aren’t actually particularly fond of milk, even if people like to think they are. They prefer water. So that might be a flaw in your theory
My cat is fond of milk, and hangs around when I’m having cereal so he can get the last bit in the bowl. Given a choice between water and milk, he goes for the milk.
As for the OP – they steal babies’ breath because they come from the Devil. That’s my theory.
Cats are curious.
Babies probably have sniffy breath.
One of my cats has a fascination with my armpits. He burrows into them when my hands are behind my head, as well as overindulging my shirts-to-be-laundered. I don’t know what his attraction is; I find it comical but rather annoying.
My 22-year-old cat likes to lick my armpits. Weirdest thing in the world. She sleeps on my bed 18 hours a day, and when I go to bed, she curls up on my chest or in my arm. When I’ve been working hard physically, I take a shower before abedding, and she goes and licks my armpits.
I find the story of the cat that sniffs tonsils perfectly believable. A mother would be freaked out by the cat sticking its nose down a baby’s throat; a religious mother would create an improper myth to keep cats out of crib rooms.
