Kitten vomit!

My 10-week-old kitty, Aphro , vomitted yellow chunks/liquid (what appeared to be her dry kitten food and Catsip). I haven't changed the type of food lately, but I do free feed her now plus a little wet food twice a day. She was meowing like crazy and then I heard some hacking.. over a period of about 3-4 minutes she vomitted 4 times. Should I bring her to the vet only if she continues to vomit ? She hasn't yet and it's been about 20 minutes and she's running around as playful as always. I suppose I'll try to feed her a little wet food. Any suggestions??

Oh yes.. and she's very non-cuddly and very anti-touch =( right now...

First off if you free-feed a kitten they will eat all the food in sight regardless of how full they feel. I would step back and feed her small amounts of food about 6 times a day. She only has a 10 week old stomach, so feed the stomach, not the bowl. If she keeps vomiting, you should get her to a vet, because at that age losing fluids like that is dangerous for their health and well-being- also mix some pedialyte in with her water- if she is drinking water out of a bowl yet?

Has the kitten been tested for worms yet?
