Puffing up in her sleep?

[giry76]

I have seen Doris do this a few times: She will be in a normal sleep ball either in her litter box :rolleyes: or when I have her out and then she will puff up into a bigger ball and kind of squeak or cry for a few seconds and then she will go back to normal size. Once I woke her up because I thought something was wrong, but she doesn't wake up on her own from doing this. Is she dreaming? Is she constipated? Something else?

Any insights will be helpfull.

I've often wondered about the same thing. Quillson won't cry in his sleep, but he'll hiss in his sleep... I wonder if he's dreaming... POor thing, nightmares suck.
