It is anecdotal but every cat ive ever gave a bit of tuna to was instantly obsessed with getting more. I close my cats in another room these days before opening tuna and have for years now after having previous cats in the past become huge nuisances when trying to open any can at all after giving them a small pinch of tuna for the first time.

Im sure there are other meats or treats that might evoke a similar response in a lot of cats, but I don't exactly have a lot of shredded pure meat sitting around to give to a cat to try.
