since you’re so dedicated I’ll give you the exact numbers, but I might change how it works in the next version so we’ll see!
Things cats can scratch (posts, cat grass, sofas, curtains) count as 2 toys. Cheap toys (balloons) count as half a toy.
It takes a “toy value” of 210 to have 20 cats, and a value of 663 to have 21. that’s the hard cap, and it can’t be raised above that.
since toys are kinda messy and take up so much space, I might change how it to just be an upgrade you can purchase to raise your kitty limit.
