I fed this to my Golden Retriever and he hated it.  He wouldn't eat it, and when he did, it gave him terrible diarrhea.  We will not be buying this again.  It's also super expensive.

Ex Output:
Negative

I normally bake from scratch but when I saw this pink lemonade cake mix with matching frosting I just had to try them both. This cake can be made two ways: with or without egg yolks. I recommend with as the cake will be nice and moist as a result. This cake would also be just as good with plain white icing or just a dusting of powdered sugar. You can make it as a layer, bundt, or sheet cake, or as cupcakes. I picked it up at the grocery store recently for about $1.80 per box, the frosting was about the same price per can. I ended up going back and purchasing more for later as I believe this is just a seasonal flavor and Pillsbury will pull it from the market at some point. If they do I hope they bring it back every spring. Until then I'll be stocking up.

Ex Output:
Positive
