Hi, I am also concerned, but I feel that I have the solutions to my problem. First, if the feral cat is pregnant, it costs an extra 20 dollars and I have 100 on my account thanks to someone special on the boards. It is 45 regularly and 65 if they are pregnant. That leaves me almost enough to get one kitten spayed. I have four months to come up with another 45 for the other kitten. The flea problem has been solved thanks to donations of a three month supply of advantage. The worm problem has been solved because of donations. If there is a major medical problem, I will not be able to do a thing. Even if I had one cat, I would not be able to help them. So far, in my life of having cats, nothing has ever gone wrong except fleas and worms. I feel blessed. I do live on a busy street and I have had four cats hit by cars. They died instantly. I try to keep them inside, but it is truly impossible because I have five children and all of their friends running in and out. The cats are very fast. When they want out, they find a way out. Thanks for your concerns and I hope this letter answers all of your questions. Love Rebecca
