Your pet must be at least an adult for breeding. Each adult pet can only breed 5 times in their lifetime, imbued pets get 3 and a mutation boost. If your pet has both been trained and imbued they have 8 breedings.
Adopts can be cross-species bred, but the farther apart they are, the more chance your litter will be a miscarriage!
These pets do *not* have assigned sexes, gender them however you like but sex will not affect breeding.
You can breed your pets together! Message other pet owners and arrange breedings to get the most out of your adopt breedings!
You can also ask do adopt from in-progress litters directly from the caretakers, they can price these babies at whatever they like to fund future breedings but they must transfer ownership to you here for it to be recognized.
Each litter costs 20

and the fee can be split between the breeders, litters between 2 owners will always be even, even with an odd roll and will always be rounded up.
Litters can also be split and gifted to other users, however they must reply here to get official ownership and breeding rights.
These things take time so be patient.
