My 20 month F is having health issues and I'm not sure what caused it. Today she regurgitated the rat she ate yesterday. She just shed a few days ago and ate quickly and enthusiastically. While walking around the neighbourhood with her today (as we sometimes do) she regurgitated her rat. Could this be from motion sickness? Perhaps we went walking too soon after she ate?

She had contracted a nasty respitory infection about 8 weeks ago, got antibiotics and recovered. She's recently starting to show signs of it returning (audible breathing, clear liquid from the mouth, puffy throat). I've increased her heat and have been giving her lots of misting. Her shed was good, and she ate her meal, so I'm not sure if the puking and this cold are related.

Other than her recent colds she's always been very healthy.
Anyone?!
