The cats where I live might be 'cool, independent & free' but they are such a blight on the environment & neighbourhood that the local municipal authority is intruducing compulsory registration of all cats, and I understand it also includes some rules about desexing (I'm not a cat owner so I have not researched the rules fully, but I think its long overdue that some rules were put in place)
The cats in my neighbourhood kill the native birds & animals, but seem useless at catching mice, and they just treat the whole area as one big toilet.
I think Joy is right about cats being uncaring - they seem to be the 'love em & leave em' type happy enough to use someone to stroke them & make them purr, but with no real loyalty to anyone or anything but themselves.
Maybe Italian dogs are different to Aussie dogs - we see dogs as our best mate in Australia, and subjugation is an alien concept in Aussie mateship :)
