What mechanical benefit does retracting the claws provide for a stalking tiger?

Answer

It allows the tiger to walk almost silently by muffling approach sounds.

Retracting the claws prevents them from dulling on the ground and, critically, allows the tiger to walk silently on the soft pads of its toes, avoiding audible scraping or clicking sounds.
