Awww, love it when our animals give birth. I've had two litters of puppies (well, not me personally haha).
With our first dog, she had 6 beautiful puppies, we arrived home and saw the last 3 being born.
With our second dog, she had 13 puppies and watched them all. At the end of the delivery she was understandably tired, so we had to help rip the sac open so mum could lick the baby and eat the placenta. She was a very full dog that evening, having eaten 13 placentas - let me tell you.
Gorgeous moment and experience, really loved playing an active part in her birthing process. She did us all proud and that's a beautiful memory. Are you going to keep the kittens or re-home them?
