In addition to being fed regularly, pets must often be played with. Playing with a pet keeps their happiness level at "Elated," which, like hunger, allows them to participate in pet-related activities. After being used a certain number of times, toys will break and disappear from a user's inventory. The number of times a toy can be used without breaking doesn't appear to be static, and can vary from toy to toy. Toys can be bought from Tinker's Toys, but they can also be received as game or battle prizes. A Playset, purchased from The Top Hat, will allow you to play with all of your pets at once and will not break.
