Healthiest treats? Any suggestions?

So as of right now, I have a couple of bags of treats that I rotate to see what my kittens like the most. The ones I have are Temptations Dairy, Beef, Friskies Crispies and Get Naked Kitten Health. The Friskies I don't feed them often, they prefer the Beef and Kitten Health Treats. I have also fed them Purebites Chicken treats which my ragdoll has finished. 

What do you feed your kitties, and what do you recommend?

I only feed my cats freeze dried meat or liver treats. They're without question the healthiest, because they're nothing but meat or liver. :lol3: Pure Bites, Whole Life, Etta Says and Stewart's ProTreat (by Gimborn) are the ones I use. Freeze dried chicken, lamb, salmon, shrimp, and chicken liver, beef liver, and lamb liver.

To be honest, I feed my cats treats SUPER rarely so I mostly just give them what they seem to like the most- Smart n'Tasty cat treats.  I read the labels of wet food religiously before I give it to my cats but in terms of treats, they each get an average of maybe one a day (except for on nail clipping days... sigh) so I don't sweat it and just give what they like.  If you are concerned about it though, I am sure others here will be able to help!

I use Pure Bites also, chicken or liver,  I also just discovered freeze dried lamb lung, by Superior Farms Pet Provisions.  OMG they are wild about this! You just need to be careful with this because pieces are on the large side so you have to break it up.  

I've used natural balance rabbit ones. The cats loved them!
