seeking good treat recipe

hi I was wondering if anyone had a good recipe for a cat treat that makes alot and doesnt need to be refrigerated. The refrigeration thing is no big deal, just easier.
I wish they sold bulk cat treats, or just bigger bags like for dog bones. Those little containers dont last long with 4 hungry cats watching it for any sign of movement!!

I've never made any treats myself. I've always bought them...to me that's much easier!

Do you have a Sam's Club near by? Sometimes they have cat treats in bulk quite cheap.
