"My ferret shadow went absolutely nuts the first time I set a "fry" next to him. But, my other boy Blizzard wouldn't touch them. I put some in his mouth and he went crazy! Every time they see the pkg they start climbing and going brzrk! I tried other treats and they didn't even care. When im teaching my babies tricks and they can't get it i take out my fries and they do excellent! THEY ARE THE BEST I RECCOMEND THEM DO NOT BUY OTHER TREATS! ONLY, I REPEAT ONLY BUY THESE AND YOUR FERRETS WILL LUV YOU 4EVER!"
