Cutting kittens cords. DO NOT CUT!!!! There is a better way. Once the cord is no longer filled with blood, wash your hands thoroughly, disinfect. Hold the kitten and massage any fluids in the cord back into the kitten. Then using your fingers, carefully pinch and cut the cord with your nails pressing the cut edges. That seals it so the kitten won't bleed.
Or you can tie off the cord with thread that has been boiled or dipped in alcohol (sterilized), tie and cut beyond the knot, but the finger one is easier and doesn't leave a residual knot.
I used to raise and show Himalayans/Persians who make wonderful mothers once their kittens are delivered, cords done, cleaned and dried and given back to them. Some of them are clueless on how to do that on their own.
