Pets are part of the build

Do not treat pets as a random bonus slot. With up to 4 equipped pets, every slot should support what your farm is trying to do. The current data tracks 28 pets, and their effects point in different directions: seed luck, growth speed, fertilizer, pet treats, mutation upgrades, and instant growth effects.

How I choose pets

Pets worth reading closely

My pet-building rule

Pick the farm plan first, then pick pets. If your plan is fast active farming, choose pets that speed up that loop. If your plan is long AFK sessions, choose pets that make the farm stable while you are gone. A powerful pet in the wrong plan still feels mediocre.
