Is a cactus a vertebrate invertebrate or is it not an animal?

A cactus is not a vertebrate or an invertebrate because it is not an animal. Cacti are a type of plant, specifically a member of the Cactaceae family, known for their ability to store water in their stems and survive in arid environments. Vertebrates are animals with a backbone, while invertebrates are animals without a backbone. Cacti do not fall into either of these categories as they are plants.
