@nap I had to go look it up for you!
Each recipe is put into the system as a %, so a hypothetical weird waffle recipe might be..... 40% Meat 40% Fish 20% Waffles idk.
Partial quantities if you have odd numbers of cats are rounded down.
So.... if you have 10 cats, you'll need 4 meat (40%) + 4 fish (40%) + 2 waffles (20%)
Kittens are .6 of a cat and beans are .3 of a cat.
So if you have 6 cats, 2 kittens, and 2 beans, you're treated as having 6 + 1.2 + .6 or 7.8 cats.
Soo...... you would need: 3 meat, 3 fish, and 1 waffle to feed them.
