The kitten whined a bit last night but eventually went to sleep. This morning I went over to pet him in Baby Jail and let him out a little under supervision. He immediately started buzzing and came over for pets and I picked him up, then he climbed on my shoulder and then onto my back.

This was a tactical error.

Very quickly we just gave up and let him go exploring. He spent most of the day poking around, disappearing under things, and finding places to nap. Donut and Gracie gave him a wide berth; neither were really prepared to deal with Interloping Kitten. Donut hissed at him a few times and Gracie spent much of the evening scowling and growling. She taught him some new cat obscenities which he's started repeating back to her. She is definitely Not Cool with the situation but she's neither moving toward or away from him. She's just big mad because now she has to think and nobody consulted with her before unleashing a kitten on the household.

All the crabbiness and stress seem within normal bounds of New Cat Day. Meanwhile our new friend has plopped in my lap twice putting like a madman. He's incredibly friendly. We just need to get past the initial crabbiness of Gracie and Donut.
