It could get a little crowded if all your bunnies were in your Haven at once so as a general rule you will only be able to have 3 more bunnies than you have customers. This means if you have 4 customers you will have 7 bunnies hopping round! But don’t worry, you will still have access to all your buns via the bunny matching toolbar when a customer comes in. Even if they aren't present in the Haven at the time, these bunnies are available to match with any eligible customer. Bunnies need to be the same level as the selected customer or higher to be able to be paired. The bigger your Haven gets, the more bunnies and customers you will have.
