a kittens is still inside the womb after 3 kittens ar born

Question
my cat is 1 year and 4 month old this is her second litter yesterday she gave birth to 3 kittens is though that this litter is only 3 kittens but at the night i was touching her stomach i felt a kitten is still inside her womb and i could feel the kitten's body with my hand is my cat's life in danger ? or she will deliver it in a few days or what should i do its been about 26 hours since she delivered the 3 kittens so what shall i do?

Answer
It is not unusual for cats to deliver kittens 48 hours later so if she hasn't delivered the kitten in that time pop her to the vet for a scan to make sure that there is another kitten in there.  If your mum is quite settled and happy don't worry too much, it may only have been the swollen womb that you could feel.
