Dogs are physically far superior to Cats and could beat them in many tests of strength, loyalty and tenacity. Cats, however, are usually independent and capable of looking after themselves. Not to mention Lions count as a type of cat and are rather competent predators. Still, a Staffy's tail could be classed as a weapon when they're happy, and their strength is outrageous for something that weighs ~14 kg. they're often (unjustly) used as fighting dogs due to their sheer will to never give up.
