Are any of your succulents toxic to pets? Those shown on this page are considered to be.
NOTE: This page is not a substitute for veterinary advice. Factors such as quantity ingested, animal weight and allergies determine what's poisonous to a particular pet. If you think yours ate something potentially toxic, call Animal Poison Control at (888) 426-4435 or seek immediate veterinary treatment.
Know plant names
The first question you'll be asked is, "What kind of plant is it?" Even if you take it along, the veterinarian may not know its name. When time is of the essence, you don't want it spent going through lists. Beforehand (i.e. now), check to see if any of the succulents your pets may come into contact with are shown here.
Both resources list types of plants (all, not just succulents) that veterinarians often encounter. Lists are alphabetical by common names---which unfortunately can be numerous and confusing---followed by genus and species. Since a plant can have only one Latin name, that's what I use.

Yes. Keep pets away from begonias, cycads, geraniums, lilies, philodendron, poinsettias, pothos, dracaena, ivy, certain herbs (mint, oregano, parsley, tarragon, marjoram), and schleffera. Btw, African violets are considered safe.

Bottom Line: Use common sense
Obviously it's not a good idea to risk having a pet eat any houseplant. Another reason to keep plants and pets apart is soil spillage---either by accident or "Cool! A litter box!" Cats knock over vases by nosing bouquets. Puppies chew anything. Even a hanging basket may bring out a cat's inner leopard.
