Relentless affection always seemed to work well for me. Hugs and forehead kisses until they are desperately trying to get away, and more if they come back and continue. indirect pestering.... blanket purrito?

Mine (https://michi.blue/) wakes me up while making horrible lewd meaw noises trying to fuck his favourite plushie. I recently found out that if I throw said plushie to the wherever the fuck I can from my sleep deprived ass in the bed, he shuts up

I give up, pat the bed beside me where she jumps up, demands some pets then eventually curls up on her own special blanket and goes back to sleep for a couple hours.

I once woke up to one of them standing on my back, paws on my head, smashing my face into the pillow so I couldn't breathe, just shrieking at the back of my head.
