The Funkitty™ Egg-Cersizer™ toy is a treat/feeding ball that randomly dispenses treats & dry food. It is uniquely adjustable to your cat's level of play. Open 1, 2 or 3 holes to customise to your cat's needs and increase the challenge over time. The Treat Meter™ prongs randomly pop out treats from all angles. Have a cat who needs to lose some weight? Feed your cat each meal in the toy for more exercise and portion control in one fun package.
