I will only ever trade one of my pets for the following reasons:
I decide that i don't like the type of pet
I decide that i don't like the name of the pet
(These things are simple enough to change though, so if i really cannot be bothered to change them then i may decide to trade, in which case, this will only happen if they do not have any of the list below with them):
Weapons, CDs, DVDs, Instruments, Minipets, Books, Spells, an Education, skills or costumes. Do not ask to trade unless it says in my blog or profile that i wish to trade! You will be blocked if you ask! My pets belong to me and are loved and don't want to go unless it says!
