Indoor cats live longer healthier lives on average.
Anyway, you're a shitty person. No one would ever improve anything if everything else had to be fixed first. You can always come up with some excuse for something else that needs to be improved before you hold yourself accountable for your own actions. No, this is all a lame bullshit excuse because you don't want to do the right thing. It isn't about other people. It's about you being a lazy selfish asshole.
