Cat Battle Armour (€377/US shipping only) by Etsy seller snaububle who sez:
Cat Battle Armor is a for-reals armor harness for your kitty. Completely hand-made from durable veg-tan leather, this is no mere costume piece. Your cat will become an unstoppable force for slaughter in this fully articulated suit, shielding him/her from foes while allowing unimpeded movement across the battlefield or living room floor.
The imposing torso section features several riveted, articulated plates and a terrifying rack of dorsal spines. Your cat’s hindquarters are sheathed beneath exquisitely arrayed overlapping scales stitched to a soft leather backing, adorned with nickel silver dome rivets. Midnight black scales and plates are finished with a glossy protective coat and seamlessly join together like the petals of a deadly flower. Adjustable at the collar with elastic and two nickel silver buckles, and at the belly with grommeted corset-style lacing for a secure, comfortable fit.
