Raising Pet Level
Pets can level up in two ways:
Feeding
Use fruits as food. Each type of fruits provides a different amount of EXP.
Using other pets as level up material
Capture pets in battles and use them as material to provide EXP for your main pet. The EXP provided by a pet-material varies depending on its species, rarity and level.
When the pet reaches level 100 and 200 it will randomly raise a level of the skill.
*notes. You can reset them if you did not get the level of the skill that you wanted with Pet Salad
