Because... it's cute and gross.

Tip will sometimes nap hard enough to drool (mostly bc she only has one fang instead of four) and will wake up and sprinkler-shake her head

occasionally I can scritch her under the chin/around the ears to get her drooly-happy, but she doesn't usually shake after that, just licks her chest/paws really hard

JJ has a gap in his front teeth and he has vampire fangs permanently.... so he happy dribbles a lot.

and I don't think Oscar drools, but he does have what we call his 'drinking problem'

which is that he LOVES drinking from the faucet, he loves it so much he will just let his whole head/face get wet doing it and then sit there and act like we're wrong for turning the water off before he can get it in his ears

... OSCAR

Bluey used to happy dribble but thankfully he didn't shake his head XD He just wanted to tuck himself against my neck as close as possible and continue drooling

Bluey was a sweetie

No but sadly Niffler does this from time to time. >.<

Lily does this sometimes. And it's always like '....ew. Thank you. Ew.'

Rhys drools while he grooms my hair!

Dana does this sometimes. lol It really is gross but also funny.
