PLEASE HELP. One of rubys kittens..(now 3 weeks old) has always had a larger head than the rest and has a slightly odd look about him. however he was the first to properly walk and has seemed perfectly normal. however today when they all got out to play he is unable to stand and his head is really floppy. im unable to make mummy interested and he seems very hungry. i think im maybe going to loose him. what should i do?
