Right now there is no way to remove a pet perminantly from the game, later overpopulation of unwanted pets will be a real issue; trust me.
I think we should have the ability to release a pet into the wild, "deleting" it from the game. If it has no offspring it can be completely erased, no data need be stored on the server. If it has offspring some data will need tobe saved obviously to track inbreeding.
Edit: Removed content about releasing wild pets. This has been shot down repeatedly and likely will not be happening. Please focus on the other suggestions in this post.
Finally I also think it would be nice to have another "structure" called a Reserve. Think like a wildlife reserve. It would essentially be for retirement, pets sent to the reserve would sort of "revert back to the wild" and couldn't be used for breeding, battle, exploring, or anything but their data and images would be saved.
This is for pets you no longer need for breeding or anything but they have some other value to you, like emotionally or something. For some reason you want to keep them but they are just taking up space in your stable that could be holding something that had more than sentimental value.
Perhaps, as a real-monies rare item, reserve pets could be re-tamed later.
Edited a bit.
