Kimmy,

What you have seen is feral cats in action. The longer the kittens stay with the mama, the more feral (wild) they become. The only way you'll be able to catch them is to humanely trap them. It takes time and patience. Once they are caught, you will need to put them in a cage in a quiet room with music and soft lighting, and food and water. The main concern is trapping the mama and having her fixed. That will also take time and patience. It's a huge undertaking by a single person. I know because I've done it many times. What you might want to consider doing is calling an animal rescue group in your area to see if they'd be willing to trap, neuter and release the adults. The kittens might be able to find homes providing they can be socialized.

If you want to help them with shelter, go get a couple of 20 gallon green storage bins with tops. Cut a hole in the side and flip it upside down on it's lid. Fill it with newspaper and straw for insulation. This will give them some place to go if the weather gets really bad. Keep water and food dishes around with dry food so they have something to eat. See if the guy you talked to is willing to pitch in.

It's sad that irresponsible pet owners think it's okay to just let their pets go to "fend for themselves". THAT is a big misconception. I commend you for your concern and hope you can find a rescue organization willing to help. When I get home tonight, I will post again with links to organizations in your area.

Good luck girlfriend. Let me know how you make out.
