Tobi - Well the reason why I don't let my cat go out often much this year he has been killing other wild animals and bringing them inside my home last year, and another reason he fought with another cat before and caught an infection which had to be treated quickly which was pretty bad, my cat doesn't get along with any other cats therefore very territorial but cats have been coming near my neighbor more often in this year than last year. Yes I agree with your last statement cats sniffing other cats scent which can be a problem.

Lora- Who would of thought hearing cats at night mating lol
I was kind of thinking the same, cats tend to be fond of me and content.
