I just opened a new bag of this food a couple of days ago. My cat sophie threw up yesterday and 2 days ago...just a little food. She throws up once in a while...always has..like once a month or so. I completely trust this dogfood. She's running around and playing like a crazy cat today. She's using her box perfectly...no accidents. Water intake seems normal. I'm just paranoid I guess. I'll keep a sharp eye on her.
