Pets will automatically level as you do. When you gain a level, your pet gains a level.
You can train it up to Mega, enter it in Pet Derbies, and hatch a pet with it.
You have to train them in the Pet Pavillion. When they level up (teen, adult, ancient etc.) they will get new talents. Which talent you get is pretty much random though.
The pets have to be adult. Take the pet to the pet pavilion and play games with it, the xp builds up and the pet goes from baby to teen to adult (you have to be a lvl 5 wizard to go to the pet pavilion) and the pet pavilion is in the commons.
Well it depends what level it is. If it is significantly lower level than the monsters you are questing on. Then go to a mob who's level is equal or just higher than the pets level, then just keep killing them until your pet levels up. Then keep doing that until your pet is the level that you desire. Or you can just 'Tame' another pet that is your level.
Dun no
play with it!
Level it up.
You can't get adult pets on happy pets, you have to raise them your self. But if you have a nice neighbor, with an adult pet they would be willing to give to you, then they can put it in the adoption center thing.
To add more than one pet in the menagerie you simply follow the same method as your 1st pet: click on pet and 'use' on pet house (assuming you have built a pet house ) remembering that the amount of pets you can deposit is dependant on your construction level i.e level 37 up to 3 pets, 52 up to 6 pets and level 67 up to 10 pets. To remove pets from the menagerie, click on your pet house and click on your pet from the menu, which will return your pet to your inventory.
You cannot evolve on epic pet wars, you simply level up. You can level up by doing jobs, winning battles, or using special battlemaster items.
You go to the Coltan's Shrine and if your lucky you may just get a level up and you can also level up by playing in the battledom alot.
