Lito, I understand your frustration with the four-month breeding time limit.
But I don't think your solution would work.
The first problem is that most of the cats sold are bought from breeders, not KittyCats. So KittyCats does not regulate those prices and would not require breeders to provide food for the cats they sell.
And as a breeder, I will say that having to wait six months between breedings would be horribly frustrating, for a variety of reasons. Discovery of new traits would essentially grind to a halt.
You do have some options now. You can turn off breeding in your cats (which cuts food consumption in half.) If you turn breeding back on around the 100-day mark, you can have one kitten before the pair of cats ages out, and it will cost you less than 350L per cat for food for the entire period.
The best news is that, whether you breed or not, you still have all the fun features of KittyCats to play with - the butterflies, the cute poses, the cuddles, the sassy comments
As pets, KittyCats are a truly outstanding value. I have given cats as presents to friends who are not breeders (and don't intend to become so) and they tell me their cats are a lot of fun!
