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)).

On top of the delightful aspartame, this comes complete with hydrogenated oils and is a dead ringer for Country Time Lemonade mix.

I simply don't like it. It is easy to prepare, but when I eat it, I feel that i am eatting a lot of artificial ingredients. I cannot even finish one fourth of it.....
