How about calling an animal shelter like ASPCA or something? They should know what to do in such cases. They might come and take the cat with the kittens and put them for adoption.
self-made, my co-worker, who rescues cats on a regular basis, told me that they will put the kittens to sleep, because they are wild. So, in order for them to take them for adoption I have to tame them somehow. How am I going to do that if I cannot even catch them? I am upset.
I can't believe they are going to put them to sleep! That is so stupid! They are supposed to protect them, not kill them. Very strange. But if that's the case then I guess the only way is for you to feed them, earn their trust and tame them and then give away to a shelter.
