Is my cat going to die?

Ok heres what happened...(flashback) Earlier today my little science geek brother told the family that one of the moths in his experiment got out...So I thought real big deal(sarcastic) when we got home I saw the nasty little bugger in my room flying around...ewww well anway my cat was chasing it around...I left to get my brother and I think my cat ate it and now she's throwing up all over the place. Is she gonna die?
