Add these.

PvP, 5-10 cat food reward depending on how long it took for you to win. Add Usernames for PvP and other stuff. Make the description of cats show health, damage, defense (If any :D), what enemies that cat can kill quickly, restisances, What dogs or other cats (from PvP) kill YOUR cat quicker. Add the "Hockey Cat", it will have a hockey mask and a machete at first level, when it evolves it gets a new name called "Serial Cat" and a new chainsaw. at last evolushion, it gets a final name of "Killer Cat" with a chainsaw in each hand, attacking with basic damage but at an EXTREMELY fast speed. The price of XP for upgrading should be really pricy, because of the cats amazing features. I will rate this game 5 stars 10 times in a row if you add half or all of these mechanics i listed. Great game, but nontheless, it could use some improvements :P
