how do you get more space for your pets treasures please put when you answer

awards 1-3 slots. there's an item in the cash shop that awards 10 slots, i believe.

You can buy in the Millionaire center which will increase your pet's treasure space by 1-3 spots; there's also a Cash Shop item which can provide more. You can also get space increases through random events.

Magical Keepsake Boxes from the Millionaire center increase your pet's treasure. There are more but I forget. ^^

thanks.
