Skipping the question about the whole ethics of having pets:
So, my cats are outdoor cats. Always have been. And, honestly, I've never ever thought about is it good or bad. Well, I assumed it's good, because... it's good - they left whenever they like and come back whenever they feel like it and who am I to keep them locked in a flat. Yes they bring a mouse or two per year, one bird maybe once in two years, but that's how life goes, right? Predators hunt. Yes, they not even hungry, but people made them like that, so what?
But today I've stumbled upon an opinion that outdoor cats are big no-no. Not every their kill they show me. And it's my duty, as a member of specie that made them like so, to hold them isolated from wildlife.
I'm feeling very conflicted. I can understand the reasons for keeping cats indoor only. But... I don't know, they are used to it.
So, what do you think?
