;-; Sorry to sound silly ! But i have no clue on how to bread my little beauitys ! I do have a male and female and they are both adults.. but it wont come up when i enter the breeding grounds o.o ?

When you go into the breeding grounds, the first thing you have to do is select the species of pet that you're wanting to breed from the drop down menu at the top. The pets that are available to breed will then be able to be selected from the two drop down menus located just above the 'Possible Offspring' section. After which you can select the 'Breed Pair' Button at the bottom left of the Breeding Grounds. ^.^

When I checked your stables the only available adults were the 2 sylvorpa. While both should be able to breed at the moment, I noticed that the female, Che is up for breeding with a 1G breeding fee. While males can breed with as many females as you like in a single day, the females have a recovery period. You can see females that are currently recovering in the breeding grounds by de-selecting the 'Exclude Recovering' button in the top right corner of the breeding grounds. (You still won't be able to breed them though. ^.^')

You can also see if a female pet is recovering by looking at the bottom right of the genetics section of their profile. It should look something like this:
*Mated with Un-named* - In Red
Recovering Until: 8/24/2016 at 10:21AM - In Green

It's possible that when you tried to breed the pets before the female was recovering and thus unable to breed. If you try it now it should work. ^.^ (Provided someone else doesn't get there before you. ^.^')
