not to worry you and could not be the same as mine, but my little baby had lots gas to and it would run you out of the room, it would make your eyers burn. come to find out it was cancer , so plz have yours checked out that can be a warning sign
What has she eaten today? Do you think she has got hold of anything she shouldn't have? Is this a sudden thing? Has she vomited or been off her food, and is she pooping normally, or does she have constipation or diarrhea?
Maybe keep a careful eye on her the next few hours and if she seems worse or develops any other symptoms, then take her to the vet to be checked out. Also I would say that if this goes on longer than a day or so, even if she doesn't seem so bad in other ways....it still might be wise to get her checked out. It might be nothing at all to worry about. Or it might be a sign something is a little wrong either in her gut or with her pancreas or liver etc.
