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: It's high-quality and the price is right, especially with subscribe-and-save via Prime, but after months of trying to keep up with my subscription, I had to put it on hold.  I'm not a big water drinker, but this stuff has a distinct flavor and when you're using it as a work-out beverage four or five times a weak it eventually wears on you.  Or me, at least. I'd still recommend it, just don't OD the way I did.
Example Output: 4

Example Input: You can't beat the price and taste of this coffee. It will always be my first choice to buy. My husband brought it home one day because he liked the price and thought the the can looked neat. Little did we know it would become our new favorite.
Example Output:
5
