Beasts you capture and raise at the Beast Cage. Each has an active skill you trigger when it helps most.
TL;DR Level pets in the order the game unlocks them, fire the right skill before the right moment (Hyena before construction, Lion and Tiger before fights), and save Wild Marks for SvS.

From community guides; effects scale with pet level and the numbers may change with updates. Different pet skills can be active at the same time.
📈Leveling & refinement
Level pets with pet food. Every 10 levels a pet needs an advancement, which costs extra materials: Taming Manuals from Lv.10, Energizing Potions from Lv.30 and Strengthening Serums from Lv.50.
Higher-rarity pets have higher level caps, up to Lv.100 for the top pets (per one wiki).
Refinement uses Common or Advanced Wild Marks to roll extra stats. A roll can come out worse, so keep the old stats if it does.
One wiki lists pet adventures at 10 Chief Stamina and 4 hours each, for random rewards.
🎯When to fire which skill
Cave Hyena right before starting a big build, especially on SvS City Construction day.
Musk Ox on gathering-scoring days.
Cave Lion, Saber-tooth Tiger and Mammoth right before a rally, garrison fight or Bear Hunt.
Snow Ape and Iron Rhino for rally leaders who want bigger marches.
On SvS Beast Slay and Power Boost days, Wild Marks and pet advancements score well (an Advanced Wild Mark is worth 15,000 points), so save them.
