Advice for a Newbie to KittyCatS?

[Oselkhandro Resident]

Well, I am a newbie...have been at this now for about 40 days..and the food costs are getting out of control. Should I be deleting all my Genesis/starter cats? Or is there a good reason to keep trying to breed out their hidden traits? I have not gotten any "new" traits, and precious little other than Genesis except when I go buy a 9T breeder to mix with the starters, and even then, its unusual to get much beyond Genesis. What do other people do? Menagerie my starters and just go buy breeders? I guess I am reluctant to waste the newer kitties (like the Advent kitty), but they seem to be so costly in food. Any thoughts on this are most gratefully welcome!
