t worry too much about the
vomiting, unless your
cat is also showing other symptoms-lethargic, no appetite, not playing, or fever.
Just keep your eye on her. Cats have very sensitive stomachs-they are barfers. Lol. Does your cat excessively wash herself? If so, then it could still be a hairball issue. I would giver her some hairball remedy once a day for a few days, just to be on the safe side.
Keep us posted!
