Wow, this was an odd thread. Back and forth the whole time. Anyways, I'm with Wendy, and I've seen it in the leo's I keep. I don't keep many, my collection stands at 5 (when the 3 come in Tuesday), but the 2 here love pinkies. Yes, I do plan to breed them, and yes pinkies will bulk them, but I'm not feeding them pinkies just so I can get eggs. They truly do seem to enjoy them.
Plus, Christina, (I'm not saying this to be rude at all either), Frankly, I don't care what you're learning in your pre-vet classes. They cannot teach you the personality, or feeding mentality of every single leopard gecko, or every single specimen of animals you could find. If you are so willing to believe that these animals don't have the mental capacity to differentiate between "I've had this everyday, this is boring" and "hey, what about those other things I get once and awhile" you're underestimating the animal. Animals are usually a lot smarter than we give them credit for.
Plus, in one of your posts, you said something like "they dont like variety, they just like something different, a different kind of food" Isn't getting something different than the norm, also in turn getting a varied diet? Don't the two points of view you used juxtapose themselves equally, not creating a different fact?
Just my 2 cents, and let me reiterate, Im not trying to start any fights, just putting my opinion out there.
