I have had this cactus for over 25 years in this pot; it was a single finger when grandma gave it to me. It is even bigger now than the picture I sent you. I am afraid to split it or repot it --don't want to kill it. Any help would be great. Thank you for your time
Some fresh soil would help. Here's a great article about repotting cactus. Good luck with this.

How often do I water this cactus? Sorry to sound so stupid but this is my first cactus and I don't want it to die. Will it bloom and how fast does it grow? Thank you
You are in hardiness zone 7a so you will need to bring it inside during the winter. This cactus is only hardy in zones 10 and 11.

Try repotting it into a well-draining container about 1 or 2 inches larger in diameter than the one you have. It looks crowded and that may be its original store container. If the damaged parts darken you can carefully cut them out.

I have tried to find them online and I can't get a defendant answer. Thank you.
Pinning down definite ID's on cacti will be a monumental task. Most have very similar care, so an ID will not be completely necessary to care for them, fortunately.

My cactus was recently repotted and is still wobbly. I am wondering if I should remove some of the pups and replant them. Should I/how do I do this? Attached are several images of the cactus.
Sure, it wouldn't hurt to remove a few! You will need thick gardening gloves, or tongs to remove them.
