Ex Input:
These are great beans for the price. If you live in a big city, however, I'd suggest buying green beans at a local Ethiopian shop or even a community Coop. I also remember a Pea berry out of East Timor that was outstanding, but this Tanzanian Pea berry is comparable to standard beans.

I've tried it with both my cats, several times. Every time they eat this, and other Whiskas Temptations products, they vomit within minutes. They LOVE it, they WANT it, it's CHEAP but it makes them puke, so, I'd consider this a bad purchase.

I have been giving my dog this treat for a long time,I found it here on Amazon and it is much cheaper! Now I learned that ALL chicken treats for dogs (and also cats I believe) that are MADE IN CHINA are being investigated  by the FDA because some dogs have died after consuming them. These treats and all Dogswell treats are made in China,I researched all over the web about this matter and bottom line is: why take the risk? A few sites say it is OK, most say to be cautious and others say don't buy.I threw out all the ones I bought and got new ones made in USA.I wish Amazon gave us the choice of "made in USA", for now I recommend everyone that has a pet to read the labels of the treats and food. Sorry this product, I don't recommend.
