Hmmm
let's see
Dogs PROS -
Can chase a stick if that floats your boat.
Easy to train due to their obsequious servility.
Can sniff out drugs if you are short of some.
Doubles up as burglar alarm.
CONS -
Nearly all hideously ugly and smelly,
happy to just defecate on the road without clearing up,
heads shaped like bullets,
coarse, greasy hair,
too thick to walk themselves,
try and procreate with random people's legs,
sometimes randomly kill people,
view letters and deliverers of letters as a potential threat,
stupidly protective of their environment,
completely undiscerning in showing loyalty to their owner (this is NOT a pro, following orders mindlessly is no excuse),
if u have a useless hand in poker you are a "dog",
make horrible barking noises,
ridiculous fixation with sticks and bones,
very easily fooled(hold stick, pretend to throw but dont let go, watch dog run after it like complete moron, point and laugh at the stupid creature)
CatsPROS -
Are simultaneously ultimate predators and incredibly beautiful (if human would be someone like ONYATOP from Goldeneye(i think?)),
independent,
low maintenance - walk themselves,
dignified,
elegant,
discerning,
if forced to defecate in public, will make attempts to cover up their mess with nearby earth,
pay their way by means of providing a supply of dead rodents and birds,
stroking a pussy increases longevity,
bigger brothers are regarded as kings of jungle,
keep themselves pristinely clean,
revered and worshipped in many cultures including amongst the incredibly advanced egyptians,
ultimate accessory for a bond villain,
have been around since prehistoric times,
all the sounds they make are aesthetically pleasing,
soft fur, pleasing to the touch.
Will stop there though could go on almost indefinitely.
CONS -
Assume the mantle of control in the household,
do not suffer fools (DOGS) gladly,
unforgiving of mistakes,
love taking the piss out of humans(

generally difficult to train as it is beneath them.
Bottom line is that cat's are cool. All the associations made to cats in language tend to be positive. Cool as a cat, the cat's whiskers, feline charms etc whilst most dog references are negative, I was a dog in that hand, she's a right dog, you played that hand like dogs**t.
Cats rule and secretly all dog lovers know this but they're just too tight to cough up the dough for a proper burglar alarm.
