generally, just level cheap cats, for example the special cats are not too hard to level, and most rare cats are rather cheap.

If youre struggling to get XP, you can repeat EoC or ItF stages for not only treasures but also XP (this tip varies on how far youre into the game)

You can also defeat the Sweet XP stages if you think you can do them. Just get some anti-blacks and they should do the job.
