Hi, about a month ago there was an adorable feral cat who was very pregnant. I had been feeding her for about 2 months. On August 15th she disappeared for some time and when I saw her again she was no longer pregnant -- she cam back a day or two later. She seems to come daily for food and then disappears. I put food out twice a day -- early morning and at night. She will eat near me but is still quite timid. I have yet to see her kittens. Does this mean that something has happened to them. She continues to eat regularly but I have seen no signs of them yet. They are about 4 weeks old going on 5 as they were born on August 15th or August 16th. Is it possible that they are alive but not old enough to venture from the nest? Or could something of happended to them. She seems to live in the woods around the back of my apartment. Also, what do nests typically look like?
