Mamma-Mouse, otherwise known as Pudd'n, has her bad days, too.
Pudd'n has seizure like symptoms, going into little full-body fits where it appears she has is laboring to breath. It is pathetic and heartbreaking. I have managed to pick her up during her fits and comfort her during them. She will often tuck herself in and go to sleep after the fits and after a bit she will sit up, acting surprised and annoyed and often demanding treats.
