As far as I know, I'm sure they won't hurt kitties. I always find it humorous when cats eat things like that. I never thought it would taste good to them. My friend's cat, Sage, just LOVES raisins!!! She actually likes them better then those Whisker Lickens and other cat treats...which is ok for my friend. She just buys a box of raisins and gives her cat a few as a treat! Believe it or not, my old cat Socks loves asperagus!! Now, that's a strange craving!! LOL LOL
