Mix-n-Match Cat Ball

This isn’t just any cat toy—it’s a customizable rolling adventure for your feline! The 3D-printed cat ball is designed with interchangeable patterned panels, so every build can look (and sound) different.

Inside, you can load it with a variety of fun fillings:

• Filament scraps (“filament poop”) for a rattly, uneven roll that keeps your cat guessing.
• A tissue spritzed with catnip for a scent-driven frenzy.
• A bell for that classic jingle that wakes the whole household at 3 a.m.

The best part? You can mix and match fillings for a multi-sensory surprise—sound, smell, and unpredictable movement all in one. Every chase turns into a brand-new game, keeping your cat entertained and you endlessly amused.
