My cat has just given birth to six kittens. They are now three days old. She shares a box with them and is a really good mother. I think that she is coping really well but my boyfriend thinks that she is going to suffocate them. When she move or gets back into the box she sometimes lays on top of them. I think they are fine because they wriggle out but he thinks otherwise and keeps shouting at me and the cat. He insists in staying up all night to watch them. Do they really need this or will they be able to crawl out from underneath her? Please help.
