strange sounds

so as of yesterday, bela started making a new noise. it freaks me out. it is this guttural growling sound that is reminiscent of a rabid dog or demon. seriously. it is not a noise that should come out of such a sweet girl! this morning i took bela upstairs to wake up daddy. lucky him, he woke up to this grumbling snarl. hopefully this will pass soon. before this she made a noise that made me rush to her aid, a choking, wheezing noise. she is over that. please let this pass soon too.
