Here's a category idea:

dog% Basically just tame a dog as fast as possible. Maybe even cat% with the game goal just with a cat.

Or an animals% which is where you have to tame all tamable animals

I like the idea of animal% because it makes it harder but dog or cat run will die out quickly cause someone can find a seed in a jungle or spruce forest and make an unbeatable record but if it's random seed animal% that can make it interesting

Same, it I doubt it’ll become a category.

We already have so many category extentions. Nothing is stopping you from trying to route it and speedrunning it, your time just won't be on a leaderboard.
