Place a shortcut link on the pet's details page to the adopt-r-us, to prevent the database to overload with newly created pets. New users sometimes want 2nd hand pets. I am like one of them.

You mean to get there quicker? You can add it to your bookmarks. On the right hand side of the page click the tab with the little + sign.

I know I can bookmark it, but I wanted to make it like that the new users can click on a shortcut to go to the adopt-r-us instantly when they view their pets by a button on the top.. (Create a pet, "Adopt a pet" free food, spotlight, change order, etc)

New users can't adopt until their accounts are a certain age anyway. (2 weeks old?)

Oh, you mean on the pets page, I thought you meant on their profile which would be weird. Yeah, I guess that would be fine and/or useful. Though man I wish that page had less stuff to load, when you have 32 pets it lags like a mofo.
