Hi Candi
Well i too would certainly love to pay less to feed my kitties but the fact is that any breedable's main source of income is the food, and already KC food is i think about the lowest in SL.
Income from KCs is split at least four ways i believe and quality servers don't come cheap, and there are of course other running overheads.
Over the years, they have complied to a multitude of requests from us, no " it's OUR game and we play it the way WE want so like or lump it " attitude.
What i WOULD like to see however is for unpairing to be free as it can be easy to pair the wrong couple and hit the wrong pairing button, but thats for another thread.
I'd say the best wtg would be to concentrate on a small amount of kitties with well traited showns and hiddens. One can pick up some great bargains on the bid boards and the love shacks and you can build some very saleable kitties in this way for a not too heavy investment ; learn the fine tuning in breeding and you too can turn out some epics. Bring in a couple of starters from time to time, you may hit the jackpot.
The best advice though is to work out a hobby budget and stick to it, this way breeding will be more fun and less of a headache.
