I currently have four babies in my lair. When I look at my pets page, they're shown in the following order: gryphon - white unicorn - buckskin unicorn - puma

However, when I'm browsing my pets via the arrow buttons on the pets' profiles, they're shown in this order: puma - gryphon - white unicorn - buckskin unicorn

It's probably worth mentioning that the gryphon and puma are about day and half older than the unicorns. Is this a bug or some obscure site mechanic?
