I also second Karen's reply as well. No criticism was meant, just concern for the safety of the kittens. Instead of giving free kittens, you might try giving a few cans of free kitten food and vitamins when someone purchases a kitten from you. In this way, a minimum amount of money is spent but the safety of the kittens is assured. We all recommended that you charge a fee because, unfortunately, experience has taught us that, if you don't, bad things can happen to them. We already understand that you're doing what you can. Otherwise, you wouldn't have posted on this forum. Good luck.
