Tiny Paws Mobility Cart – For Rabbits, Cats & More

I’ve designed a lightweight and functional wheelchair for small animals (up to 2kg) who are bravely holding on to life despite their physical disabilities. Most commercially available carts are too heavy, making it difficult for our little friends to move or causing them to get tired quickly. We tested this design on a 1.5 kg rabbit with paralyzed hind legs, and the results were excellent.

This cart is designed for animals like cats and rabbits under 2kg. It’s especially suited for those with hind leg issues, but you can print two sets to create a 4-wheel version. You can even add caster wheels to improve maneuverability.

I used PLA filament for printing. However, if you plan to use it outdoors or in direct sunlight, I recommend using ABS or PETG for better durability.

If you leave your feedback in the comments, we can continue improving the design together and help even more little lives. The layer height and infill values below can be adjusted as needed.

1x Main Body
2x Connector Pieces
2x Wheel Mount Brackets
2x Metal Rods (4mm diameter)
2x RC Car or RC Airplane Wheels (we used airplane wheels for their light weight)
1x Harness or small garment to secure your pet (we sewed one ourselves)
8x m3 Bolts
8x m3 Nut
8x m3 Washers

You can customize the cart by increasing the number of parts — for example, it's possible to create a 4-wheeled version for better stability.
