I just happened to be watching my BP and all of a sudden he jerked his head really weird and kind of opened his mouth a little. It was the fastest I'd ever seen him move when not feeding. He looked a little out of sorts for a second but chilled out. Then he yawned once, twice, a reallllly long third time, adjusted himself a bit, did some more stuff that reminded me of a sleepy person smacking his lips, and then (I'm guessing) went back to sleep.

When his mouth was open for a long time I looked carefully and his mouth looks clean and pink like it always has.

Anybody have any ideas? Should I get him checked out or look for anything?
