Example Input: Both of my cats (age 11) threw up for an extended period after eating just 3 of these. Into the trash they go (not the cats, the treats). Not sure what they were reacting to but thought it would be good to let other cat parents know the risk.
Example Output: 1

Example Input: For those of us with celiac disease this product is a lifesaver and what could be better than getting it at almost half the price of the grocery or health food store!  I love McCann's instant oatmeal - all flavors!!!  Thanks, Abby

Example Input: Can't say much about the product itself.  was a gift for friends in California who had just given birth and it arrived 5-6 days after shipping totally melted.  The seller gave early warning before shipping stating the weather had been abnormally hot and that they could not be held responsible for packages missed and left to sit in the heat.  I assumed that was not an issue considering my wife was at their home and aware the package would be arriving and I had also purchased priority shipping (additional $8+dollars).  No such luck.  Be sure whoever you are buying these from gives you absolute specifics before you buy. Just to be fair, I have to say the seller was very quick and courteous with responses to my concerns.  Unfortunately she didn't even consider any form of compensation though.  I really hate throwing money away and giving a less than memorable gift at the same time.
