To mate, you have you give your desired sla- I mean, mate, lots of presents like things on the ground or prey. If you go into the inventory, there will be four various cats and those cats will be the ones you may be able to mate with. If your desired slave- I mean, MATE, has reached four stars, you give them a flower thingy from the cafe and boom! that's stage one! (bf gf or whatever) If you want to marry them, you have to do the same thingy over but instead of the flower thingy, you have to give them the diamond!
