If you have a mate of the opposite gender, you can give them a pink tulip and they'll ask to try for kits. Keep giving them tulips until either you're expecting or they say they're expecting.
give your mate a pink tulip it will ask you if you want to try kits. if you a male and your mate is a she-cat it will say "Oh honey in case you didn't know I'm expecting kits" and if your a female with a male mate it will show a kit symbol in the upper right
