Meowfia Evolution
This is a great suggestion for everyone looking for some untypical pet care games. Here, you become the boss of a cat mafia where your task is to breed cats in such a way that you can make the most money from them.
You need to combine two cats of the same breed to make them evolve into a new kind. Once in a while, you will get a new kitten delivery, and you will be able to develop new breeds bringing you additional money (with their poop!).
This game was made with a great sense of humor, and it shows not only by the original gameplay but also by the cat breed names, such as Furry de Niro, Al Pusscino, or Capodikitty.
