Ok so Caticorn is now lvl 37 and Ghost cat is lvl 36.
okay! to get more fishbones i suggest using computer - house, house - computer trail with caticorn to defeat the house cats easily!
and if you want to, sell uwu! although they're cute, you can always restart the game with the goal of getting all cats (my motto when i get a cute cat and remember my save with all cats..), since all levels with love as an auto-win are already defeated when it's ocean time! if not (either you left the fields level 7, or woods levels 2 or 6..) then keep them.
and DON'T sell pixel cat! they have comfort, which auto-wins the last three stages of the game.
