Our beautiful kittens are now six and a half weeks old and all has been going well. Last night my sons accidentally let the mother cat out and then, without realising, locked her out all night. Naturally I am very worried. I realise there is a very real danger that she might be pregnant, but more concerning is that she hasnt licked them all over or attempted to feed them since she came back in. Is it possible that her milk could have dried up in the hours she was separated from them? They are doing well at weaning but both kittens and mother cat still enjoy a feeding time. The kittens appear unaffected but I am worried about mum. Any advice would be really welcome.
