They accept debit at the entrance if you want food inside its cash only.

At the entrance, you can use credit, debit, or cash. Once youre inside, it's all cash. There is an ATM at the entrance. Inside you can buy more food for the animals, there is a bird cage that you can go into with peanut butter, and thats cash. There is a little food stand inside also for people, and thats cash.
