Somebody gave me this cactus that had become too crowded for their pot.

It has a lot of projections that must have reminded some taxonomist of an important part of the female anatony.

If it's OK to divide, any special precautions? (Aside from not getting pricked)

TIA


Cut however many stems you want to propagate. Use a sharp, clean knife.
Allow the cut to dry for a few days in a dry, but not too warm place.
It does not need any rooting powder or antifungal powder on the cut
surface if the cut was clean. When dry, push the cut end gently onto
clean dry sharp sand (coarse sand) until it is a few mm deep. If
necessary, support it with a few thin sticks such as toothpicks. Leave
in a cool place with good light (not direct sunlight if possible) for a
couple of months.

At the end of that time have a look to see if roots have formed. If
not, leave for another couple of months. If they have formed, pot up in
"cactus compost", or very free-draining soil with added grit. Water
very sparingly, and leave in good light in a warm place.
