Illustration servo legs for Camilo Parra Palacio :

the "Cat"-box shall be the body, one servo at the top of the leg with it's arm mounted at (inside) the body.

Servos should be (much easier) screwed from outside the legs.

In the leg is enough space for storing the servo wires and to add an extra LED for leg illumination.

If the Otto gets wider hips, the steps could be bigger for faster movement.

Would also be nice to assemble the batteries outside the body, so battery change can be made without surgery through the wires in the body.
