A feral cat had kittens about 3-1/2 weeks ago. I've been able to pet her when she comes up to the house to get food along with the other cats. She won't let me pick her up tho. She won't come near me any other time. I found the kittens right away. They are in the front seat of a junk pickup truck. She got in there thru the hole in the floor where the transmission would have been. She has no problem with me looking in on her thru the window. Yesterday we were able to get the door partially opened. She was not there at the time. I closed the door and waiting until today. I went out there and she was with the kitties. I talked to her and opened the door slowly. She growled at me and then jumped out the hole. I opened the door and picked up each of the kitties. There are 4 of them. I would like to keep touching them every day so they get used to me and get tamed. I'm concerned she is going to move them now that I touched them. Are they too young to be handled?
