Even if you have a good point people are going to be less likely to listen to you if you start calling them lazy. This comment would be better without the last sentence

fair. projection on my part. i interpret seeing people say indoor cats lives are miserable (and using that idea uncritically to affirm their own choices) are doing so from a holier-than-thou position. to me, it's an uncreative and lazy view on pet ownership, but i getcha: flies, honey, and vinegar and all that.

> walk your cat on a leash

I doubt any of the cats I've ever had would approve of this

Mine adores her leash walks. Cats are naturally skittish animals, being both prey and predator. So if they trust you as a source of protection the comfort of walking without worries is a benefit that outweighs the restriction of the harness. Plus it's high quality bonding time.

I live in an apartment complex with lots of animals and I see several of my neighbors leash-walk their cats regularly.

It just takes some time to train them usually. It's much easier if you get them used to it early in their lifetime, though.
