I am baffled as to why cat food is labelled up as having "The great all-natural taste of beef and lamb that your cat loves!" because if my cat could naturally eat beef then that would be fucking terrifying, a 4kg cat that can eat a 600kg cow.
They should say "The great all-natural taste of mice and wasps that your cat loves!" based on observed behaviour.
Thanks to tools, I'm a far more capable hunter than my cat. It's trivial for a human of any size to kill a slow moving cow. It's very hard to imagine any scenario where a domestic cat would be capable of hurting a cow, let alone kill and eat it.
Actually I'm well north of 100kg, and being a tool-using ape that's about 1/6th the weight of and considerably taller than the animal I want to eat it's a fairly easy task.
If I was 1/150th the weight of a cow with my eyeline roughly level with the top of the animal's foot, armed with teeth about 12mm long and sharp claws about 5mm long, I suspect it would be considerably more difficult.
