I know I will get flamed for this but these are my opinions and I am entitled to them. The following pets I will absolutely under NO circumstances accept as a trade for any of my pets...

Ogules
Dakotas
Huthiq (unless mermaid)
Kronks
Phantys
Zooshs
NO MUMMY PETS
NO SKINNY PETS
NO FAT PETS

Yes I am aware this knockes out a huge chunk of pets...sorry but I do not like these.
