Grow a Garden introduced Pet Mutations with the update of the same name on July 12, 2025. Pet Mutations are only applicable to level 50 or higher farm animals, making it important to try and level them up as quickly as possible. The fastest way to get your Pets to level 50 is to use XP-granting Pets, feed your companions large Fruits, and get additional Pet slots.
Here’s how you can get your farm animals to level 50 at a rapid pace in Grow a Garden.
Quickly leveling Pets up to 50 in Grow a Garden

Before you try leveling your Pets up, consider unlocking at least four Pet slots. Pet slots determine the maximum possible age of your Pets. If you don’t have four slots available, your Pet will simply stop aging before reaching level 50. Sell unused Pets to unlock new slots and increase the Pet level cap at the same time. That way, you won’t be wasting much time while leveling up your Pets.
There are a few ways to improve your Pets’ XP gain rate so that they reach level 50 as soon as possible. These methods borrow from all aspects of the game, which means that there is plenty of legwork to be done if you’re a new player. Use all three simultaneously to reach the desired level at the earliest.
- XP-granting Pets: Certain Pet passives, such as the Night Owl, grant bonus XP per second to all active Pets. Stacking such passives will help you significantly improve the level-up rate of your farm critters.
- Feed your Pets: If your Pets’ Hunger Meters are fully depleted, they will stop gaining XP. Consider topping off their Hunger Meters every 12 hours to ensure they continue to gather XP over time. Larger Fruits like the Horned Dinomushrooms grant bonus XP, so be sure to reserve a few for this.
- Pet Toys: Pet Toys are a new addition to the game that can be crafted for bonuses to the Pet XP gain rate. The Small Treat, Medium Treat, and Level-up Lollipop items will all help your Pets level up, making them a great option to reach the desired level.
