Something wrong with money upgrade

Hi, Ive been playing this game for a while, and it is super fun. One thing to fix. There is a bug when you are at lvl 5 of money, the limit is 350 but its 360 to upgrade to lvl 6. Plz fix this and everyone would be able to upgrade to lvl 6 and above. And plz add more money levels and stronger cats. Thanks.
