My cat ate almost a whole bag of Purina's Whisker Lickin's. Is it bad for her?

Its not bad or good for her... She'll be ok. Just don't make the same mistake twice. Don't feed her anymore treats for a long while. Vet? eh, naw you're cool. If she starts vomiting then that is a good sign, not a bad sign. Don't get scared if she vomits the whiskers lickins up on the floor. If she doesnt vomit then they'll come out in her litterbox...
