You know, I was searching the Internet for the words "temptations" and "vomit" when I came across these reviews. I was surprised to hear that I'm not the only one who has had problems with this product. Within an hour of eating these treats my cat vomits for about 40 minutes. I didn't realize it was the cause until the second time I fed them to her. It's really bad because it doesn't cause the cat to throw up all at once. It's like she can just vomit a little at a time and you're forced to follow her around cleaning up all the vomit ((or locking her in the bathroom (which is horrible)).

When I got my Keurig brewer last month, I bought two different types of hot chocolate. The Grove Square Hot Chocolate is far superior. I have so far brewed it on 6oz and 8oz with good flavor at both sizes. The flavor is rich and it leaves no residue in the bottom of the kcup (the other brand does, maybe I got a bad batch?). Overall, I will happily buy this one again.

Our dog loves this stuff. I bought it for a occasional treat since he only eats dry dog food, I thought it would be a nice treat for him to have a lil something extra every now and then. But this stuff stinks really bad like dirt, it makes the whole area where the dog eats smell like we just opened and bag of soil in the house. If they could improve the smell of it, that would be awesome, because our dog just loves it but we can't bare the smell of it.
