To view a pet's info and apply points, single-click the pet and select 'NPC Info' from the menu. That stat can be unlocked for your pet's children through breeding though. If a pet's maximum level is lower than the stat unlock level, that stat can never be unlocked. Most of the stats are locked at first, but will unlock when the pet reaches the required level in the chart below. When pets gain a level they gain a random amount of ability points which can be used to distribute and increase the pets stats. A pet gains experience whenever they fight. Fresh tamed pets can have a maximum level between 9-35.
