I think to help with the gap between the beach and the wolves, you could add little chats with the furrys. Basically every stage of growth we have a chat with them. This can be generic for now, but maybe make it different for each route. And each of these chats is like a mini quest that gives an increasing XP boost that is different from the normal 2x XP boost that gets added on top. Like every victory rewards 5 bonus xp at lvl 5, 10 at lvl 10 etc. (these would be specific to the furry you chatted with. so if you have fox at 30 she gets the 30 bonus but the cow at lvl 10 only gets 10 bonus.) This will help with that gap between beach and Wolf Den, helps build up the new furrys we unlock, and eventually will be useful when we go to the lvl 100 cap you are hinting at doing.
