According to this article, domestic shorthair (that is, non-pedigree) cats are less friendly then pedigree cats:
We can certainly vouch for the fact that our cat Ted had plenty of "attitude"!
Ted was with us for many years, but has now gone to "pussy-heaven". He was definitely a domestic shorthair.
In spite of this, it seems that in New York, there's sentiment in favour of alley cats. I came across this article when looking for something completely unrelated:
Apparently in New York - and elsewhere in the US - the plan is to manage feral cat populations by the "trap-neuter-return" method. In other words, the feral cats are neutered and then returned so that they can continue to be feral! I like domestic cats, but I don't think the world needs feral cats. TNR sounds to me as an emotional response over-riding common sense.
