I don't know if anyone ever brought this up. I hatch a lot of pets, and I like to name them myself to keep better track of them. I thought it would be easier if there was a feature to rename your pets right there at the pavilion, instead of running to the shopping district. It can be added to the "pet shop boys" right there in the pavilion. As a matter of fact one of the NPC's (Lowe Springfield) is really just standing there with no function (I don't recall if he was involved with any quests) I like the fact that I can go there if I am unsatisfied with the way a pet turned out. I just sell them. So please consider adding a feature to rename our pets right there, put that Mr Springfield to work!
