The Cat Grab is an obstacle, firstly introduced as the second obstacle on American Ninja Warrior 6 in Denver.
Competitors must jump to the first wall, then jump to the next wall, and finally jump to the landing platform.
During the broadcast of American Ninja Warrior 7's Kansas City qualifiers, it was revealed that one competitor (Dennis Lappin) suffered a severe injury from this obstacle. While jumping to the first wall, his right leg hit the wall very hard, resulting a ruptured achilles tendon and needing six months to recovery.
On Australian Ninja Warrior 3, the Cat Grab appeared as the sixth obstacle in Stage Two. This time, the obstacle featured 3 walls, with the second wall being placed higher than the first and third walls.
The obstacle ended up defeating two competitors: Alex Matthew (who timed out at the top of the first wall) and Zak Stolz (who got slipped after landing at the top of the third wall).
