I won’t adopt kittens, personally. Those little shits are cute, sure, but they eat everything and claw everything and try to kill themselves on everything. Just like a toddler.
Even if an older cat wasn’t trained at all, they still get some sort of common sense level up after they pass kitten age.
I know there are some databases of all Reddit comments prior to… maybe 2015? I forget. Would be cool to port them into an open source clone that isn’t profiting off them, just for the times comments were really useful, like solving a tech issue only a couple people had ever documented.
