Maybe having a category for reaching certain amount of stars. for example 30 stars? If there is I would love to rush this category.

How about an "All cat shard shines" or "All fury shadow shines" or something like that where you have to get certain types of shines? I think that'd be cool.

Cat% give all the cat mom there cats you have have to give all 3 of them there cats, I think this would be an interesting catigory
