This guy is a beast. If you forget to water a plant, A CACTUS is the answer. But if you’re the person who over waters a plant make sure you have drainage with a cactus or else it will die. Only thing i worry about is pets going to sniff it and pricks their nose. I’m on my toes when my pets are close by to my cactus. But overall not a hard plant to take care of!
