We’ve got two young cats, both affectionate, chatty little fellas. Lots of meows and chirrups in the humans’ direction.
But sometimes, they “answer” a question with a single lick of the lips. So for example, when one trots in from the garden I’ll say, “hello, have you had fun?” - and I’ll get an upright tail & a single lip lick.
This is a form of communication, right? Google just bangs on about possible illness, but I reckon it’s “yep”, or “yep and now feed me”.
