the argument for cats > peskier than dogs will never work out, neither is the reverse. no point arguing for something that cannot be proved. this was a debate that would never end.
think about it. the cases for cats giving trouble on forums are as much as u can find as dogs giving trouble. personally, i have a friend who keeps both felines and dogs (private landed property) and both are fine to her. perhaps its the lack of training for these pets that resulted in all the unhappiness? so far i dun think strays would happily climb to the 10 floor, be it dogs or cats.
take a breather, and look at the larger picture. i'm not saying ur wrong, or nightmare is wrong. just saying u need to take a step back and realise this argument wont work
