You would have to put 4 small pieces of toast on it's feet surely? If you put it on it's back you've just got a cat with toast on it's back.

No, because the propensity for the butter side to hit the floor would be counterbalanced by the cat’s propensity to land on it’s feet.  If you put toast on the cat’s feet, the whole unit would simply land feet first.

Butter side up on the cats feet obviously, taking into account the weight of the cat 4 pieces of toast butter side up should be sufficient to counteract the weight difference.
