This is the 2nd treat our cat has refused to eat in his 17 years. He ate the first one that was offered and will not even try another one. We tried putting one of these, in a group of 3 others, and he will absolutely leave the Special Kitty one. The other treat he refused to eat was the "rope" one that was supposed to fit in the little mouse....NO was the answer to that one also. I can not imagine what is in there that he absolutely refuses to eat, but it is something. The price was right, but if he refuses to eat it....not so right. Guess we will offer them to our neighbor and see if their cat will eat them. Sorry I did not have a better experience with this product.
