Almost all domestic cats rake their toys (their “prey”) with their hind feet. They grab the toy with in their forelegs and paws and bite it while simultaneously raking the toy with their hind claws.
The addition of raking with hind claws doesn’t occur every time but frequently. It is something that cats do when playing with their caretaker’s arm too 😉 . This can be a tricky moment because the way to stop it is to relax and not fight back and struggle because if you do your cat is instinctively triggered to fight harder as if he was struggling to kill prey.
If the caretaker relaxes, distracts his cat and gently extricates his arm the cat will let go. If you start struggling with your cat in play you’ll quite likely end up with a scratched hand and arm and you’ll blame the cat!
Cats don’t usually, or hardly ever, rake genuine prey (living prey) with their hind claws before the kill. Perhaps they might once it is dead. It would be too dangerous for the cat to do it and too inefficient. Cats kill efficiently and with an eye to minimising possible injury to themselves. Killing prey can be dangerous for a cat. We see this with the wild cats all the time, especially the bigger cats. Many large wild cats are killed while killing large prey.
So the answer to the question in the title is; True, this is about play rather than a genuine kill. There may be exceptions to this general observation.
We know that domestic cats usually kill by breaking the neck of the prey item. A canine tooth is accurately placed between two vertebra of the neck snapping the spinal cord.
I can remember one visitor arguing that it was okay to declaw the front paws because cats killed with their hind claws. Wrong. Sorry.
