Welcome to breeder. You will start off with two rabbits, one male, one female. By clicking and dragging the male to the female you will initiate a "breeding session". After a short gestation period a baby rabbit will emerge. When the baby rabbit becomes an adult rabbit, it too may be involved in a "breeding session" and so on and so forth.
What to do
1. breed males to females; 2. move them out of the way of meteors; 3. move them away from the electric fence; 4. breed 8 rabbits to win the game.
What not to do
1. breed males to males (they are not that way inclined); 2. breed from pregnant rabbits (it's the hormones, don't ask); 3. let baby rabbits play near the electric fence; 4. feed the rabbits (they don't need to eat as they are not real)
