I'll start, I missed the outdoor cats struggle session so i don't know what its deal was except a vague idea that outdoor cats were bad, so I've let my two cats stay being outdoor cats because I feel bad locking them inside, like I want to give them some experience of freedom to go where they please so they can live more fulfilling lives
Edit: also kruschev is imo a lot better than most hexbear users give him credit for
No. It's a combination of culture and personal choice. Bathing practices very enormously across different cultures and such. There's probably a pretty cool youtube series on going around the world and talking about how different people wash.
