We must totally separate our own human needs from those of our pets and put the myths about pet reproduction to rest. All you have to do is look around to get the gist that genetics is the spin of a wheel. Even if you have a purebred, the pups and kittens you produce will not be a carbon of the looks or temperament of mom or dad. Moreover, your pet is the reflection of YOU and is wonderful because YOU are wonderful. So, have all those folks who want to have wonderful pets go to the nearest shelter and get a pet and then let it reflect the wonderful person and home they provide.
Birth is indeed a miracle and so is life.
Miracles surround us and blessings abound. Indeed births and passings are around us at every turn. Pets prefer to give birth in the quiet alone. If you watch, bother them, or interfere, the birth won t go smoothly. So, I doubt your kids will get to watch.
