Kobuk your not going to convince a cat owner a dog is smarter. I have
always read that dogs and cats are on a par intelligence wise.
With any species your going to find one now and then who shows
outstanding intelligence. However on average it's likely they are
much the same.
One could say a cat is smarter in that he/she takes life easy,
and stays away from danger for the most part. Where in most
cases a dog being a scocial beast is more likely to look out for
his/her boss than the usally non social feline. In a social group
layality to the leader pays benifits.
I think most cat owners would say the cat owns them instead.
