Cactus vs Succulent
Quick answer
Every cactus is a succulent (it stores water in its tissue), but not every succulent is a cactus. The practical difference for home growing: how they look, whether they have spines, and how long they wait for water in winter. This comparison covers desert cacti. Forest cacti such as the Christmas cactus need shade from strong sun, more regular watering and more humidity.

Cactus (assortment)
Choose a desert cactus if you want a structural, architectural shape and a plant that goes the longest between waterings in winter. Note: spines make them less suitable around small children.
Echeveria (Succulent)
Choose Echeveria if you want the rosette look or a plant without spines. Of the two, it is also the one listed as non-toxic to cats and dogs.
Still unsure? Take the Echeveria. It has no spines and is listed as non-toxic to pets. Both need your brightest window with some direct sun.

What is the difference between a cactus and a succulent?
All cacti are succulents (they store water), but not all succulents are cacti. Cacti belong to the family Cactaceae and are identified by areoles, specialized cushion-like structures from which spines, flowers, and new growth emerge. Other succulents (Echeveria, Aloe, Haworthia, Sedum) lack areoles and spines.
Which is easier to grow, a cactus or a succulent?
Both are rated easy and are very drought-tolerant. Both need bright light with some direct sun indoors, so give either one your brightest window. The cactus can wait longer between waterings in winter.
Are cacti safe for cats and dogs?
Echeveria is listed as non-toxic by the ASPCA. Cactus is a whole plant family rather than one species, and the ASPCA holds no record for it, so we cannot confirm that every cactus is safe. The main risk from cacti is the physical spines. Keep them out of reach of pets and children.
