A question about pet selling

[LaplaceNoMa]

Hi there. There's something I don't quite understand about how this system works. Let's say I have some pretty rare BoP pets which could be sold on the AH. What would happened to them in my collection after I sell them? Take corehound pup as an example. I got it for my authenticator, it's my 'reward' for it, I can, apparently, cage it and sell it on the AH. Will I still have it on me? Does it mean I can cage and sell those as much as I want, providing me with an endless gold source?

I'm sure I'm missing something important about all this stuff.

If you cage a pet, it is no longer in your collection. If you then sell the caged pet, you don't have it anymore.

Also, Corehound Pub (and all other Blizzard Store pets) cannot be caged (and sold)...
