Know of any good treats?

I would like to give my cats treats, but I have to avoid chicken, beef, fish, corn, wheat soy, rice, dairy, and eggs. A lady was handing out samples of Greenies treats at Petsmart, but one of them had wheat, and they both had animal plasma. That sounds disgusting! Any suggestions on some good treats? I recently threw away several bags of "junky" treats that my mother had given me.

The one ingredient freeze-dried meat or organs are healthy treats. Some of them are chicken or beef based, but I know there's lamb liver and shrimp and salmon. The brand names are Whole Life, Pure Bites and Etta Says.

Thanks!

My kitten loves purebites, you could get the purebites from the doggy section too, since they only have one ingredient in them
