Help!

The girlfriends BOA is doing some weird stuff, I'm hoping someone might know what is happening.. Our Female 5 year old BCI is opening her mouth all the way and regurgitating the water she just drank. She's making weezing sounds every few minutes and is moving like she's swallowing in reverse LOL. Oh.. she just threw up the rat we fed her last week... is this normal? we just brought her home last weekend..

Thanks,
chris.
