Can we have gathering info!! It would be super cool to see other cat from different clans!! Then cats with short legs or different types of ears! And new poses, I love this game by the way!
gathering info is most likely going to be a thing eventually. there's already a couple of events that refer to the gathering, and it's planned for there be more in the future.
All the other suggestions you've made would require incredible amounts of spritework to pull off- especially new poses, which would require Every Single Spritesheet to be reworked a lot. The team's done it once when adding special poses for sick/injured and paralyzed cats, and the amount of work put into it was insane. It'd be even more now thanks to more pelts, tortie patterns, and white patches being added each update.
So the sprite-related suggestions will most likely not be added. A mod for some of those could be neat though!
