These are like heroin for cats, I'm not kidding.
My two go bonkers for it, won't shut up.
It's like that SpongeBob episode where he buys Gary the snail treats.
Temptations are the primary foundation of how we've managed to train our cat over the years, because he will always, ALWAYS come running when you shake the package and it makes that rattling sound.
It's worked so well that he'll just come loping into the room where the treats are stored at certain times of day, taking up a seat on the floor and looking up at me, ready for me to pick them up and start doling them out.
