Quote: "Well you don't see the police using police cats, do you?"
Dogs naturally follow orders, Cats are naturally Independant.
If you notice actually the police generally ONLY use German Shepards, as these are the most obedient dog and natural teamworker, not to mention built for fighting. (not vicious though, there is a dissernable difference)
Quote: "You don't hear of cats killing dogs."
Actually i've never heard of a dog killing a cat either, but i hear more cases of dog getting the stuffing beaten out of them by cats.
Quote: "Have a look to the wild and see what wild versions of dogs can do and then you wouldn't claim cats are tougher."
Wild, where Cats meet Dogs...
Lynx vs Coyote; The Coyote knows better than to piss off a Lynx, those buggers live off Falcons - some of the most feirce of all the predatory birds.
Lion vs Heyina ... although they Heyina will come in and try to take an Lioness if it's desperate, it will only try it in a pack and most of the time one of them will be slaughtered before they decide it was a bad idea.
Closer to home; Fox/Wolf vs Manx ... Fox will not attack a Manx unless it has no other choice, and wolves go for Hares/Rabbits because tackling a cat is hardwork.
The British Cats vs Dogs would be closer than any other type of wild cat vs dog; but in the end cats are built for killing things, dogs are built to look fearsome. Wolves are pack hunters, Manx are solitary killers.
Domesticated cats have just adapted to well to suburban life getting smaller and smaller over the years. The only reason a cat is big is to catch big prey and defend from being hunted.
Remember there is a major difference in how cats and how dogs hunt and kill. A dog will use it's teeth, it's claws are not designed for killing. A cat has claws designed to penetrate and slash as well as much sharper teeth designed to dig deep into prey, this a very different from the dogs which are designed to rip apart things.
Dogs are scavengers. Built for terror.
Cats are hunters. Built for killing.
Don't let a common house cat's size fool you, when they want to they can be far more dangerous.
