Big Pets are a type of Pets in Build a Zoo that earn a lot more money than their regular-sized counterparts. Their size is so large that you need to place them in one of the three dedicated Big Pet podiums in your zoo. Upon unlocking the podiums, Pet will automatically occupy them, which can then be leveled up to increase their size and earn rate.
Here’s a guide on Big Pets in Build a Zoo.
Unlocking Big Pets in Build a Zoo

Unlocking Big Pets in this title is fairly simple: gain access to the Big Pet podiums, and the game will automatically add a Pet to them. There are three Big Pet podiums in the game: two near the front of your zoo, and one in the Fishing area.
The two near the front of the zoo hold regular Pets, while the one in the fishing area is exclusively for fish-type Pets. You can unlock one of the two regular podiums for 30,000 Cash, while the other costs 299 Robux instead. For the Fishing area podium, you need 50,000 Cash instead.
Your Big Pets will automatically be switched upon hitting certain level thresholds, but you can always swap them back. There are certain special Big Pets that can only be obtained through special Eggs. When equipped, these Unique Big Pets earn extra Cash, making them more desirable than their regular counterparts.
Here’s a complete list of these Unique Big Pets and the earning bonuses they offer:
- Ankylosaurus: +5% Cash earned
- Velociraptor: +10% Cash earned
- Stegosaurus: +10% Cash earned
