Outside of combat, one of the main things you'll be doing in Mewgenics is breeding cats. It's how you get more budding warriors with better optimised stats and skills (better than the strays that show up each day), though it's far from straightforward. Mastering cat breeding is vital as you progress into harder stages, especially as the runs get longer and longer.
I'll say right now that it's vital to send your precious kittens to Tink early on to unlock more features, such as seeing your cats' sexuality, mood, libido, relationships, and more, that'll help you better optimise cat breeding.
