Which plants are toxic to cats? How about plants that are poisonous to dogs, guinea pigs, rabbits, and iguanas? Keep these common plants away from your pets!
We all enjoy our plants. However, pet owners need to be aware that some plants are toxic if their animal has a hankering to eat them!
You may already know that daffodils cause stomach upsets or vomiting (or worse) if your pet eats any parts of the plant. Many lilies are also considered extremely toxic; this can be more of a danger because lilies are often brought inside as houseplants or holiday decorations. But you may not know that foxglove and aloe vera are quite poisonous, too.
We’ve highlighted some of the most toxic plants below. However, there are more than 700 plants with toxic substances that are dangerous to dogs, cats, and other pets if ingested, so always make sure that you know whether any new plants you bring home are toxic or not!

Are Poinsettias Poisonous to Pets?
This is one of our most common questions. Though they have a bad reputation, poinsettia (Euphorbia pulcherrima) plants are only mildly toxic to cats and dogs. There can be mild skin, eye, or tummy irritation. Due to the low level of toxicity seen with poinsettia ingestion, medical treatment is rarely necessary unless clinical signs are severe.
If your pet exhibits these signs, it may have eaten something poisonous. Call your vet or the ASPCA poison control center immediately. If possible, bring a sample of the plant and tell the vet staff how much your pet ingested.
Excessive salivation
Vomiting
Lethargy
Rapid Breathing
Racing or irregular pulse
Cold extremities
Vulnerability to plant toxicities does depend on pet species, amount digested, and the size of your pet.

Pine (Pinus spp.) is not listed on the ASPCA toxic plant list for dogs (see below) or on several other sites that focus on pet health, such as lists from some veterinary medicine schools. A few unofficial sites do say that household pine oil, or sap from certain pines might cause problems. As for cedar, it would depend on the genus; true cedar is Cedrus, but many other plants are called cedar, such as junipers (red cedar); there is not much evident that the common name of cedar appears on toxic plant lists for dogs, nor the common name of juniper (Juniperus). For best advice, though, we'd recommend that you talk to your veterinarian about whether these trees/shrubs are toxic to dogs.
There is, of course, the possibility that your dog might inadvertently choke on the smaller pieces or smaller cones (nothing to do with toxin). In this light, especially if your dog is the enthusiastic type that does everything with gusto, it probably would be good to try to train him not to chew them.

While pine is not "officially" listed as toxic, in my 25+ years of rescuing animals, I have found that cats and pine, regardless of type, NEVER mix. Whether they drink from the Christmas tree water, scratch their claws on a pine tree and then lick their paws clean, or start nibbling on the branches, they get extremely sick. No one I know has ever lost a kitty from eating pine, but a few have come very very close!
Dogs can tolerate it better, but it's still not a good idea for them to eat it. It won't poison your dog to eat the occasional pine cone, but as the staff pointed out, they do pose a choking hazard so be careful.

Thank you for posting these lists. I find them extremely helpful. Perhaps we should be noting that there are plants whose very presence can cause an allergic reaction. We purchased Poinsettias from a fundraiser and within a day of setting these two plants on the dining table, our dog developed hives all over her body. The vet innocently asked, "You don't have any poinsettia in the house do you?" They were gone the same day and her hives disappeared soon thereafter.

My indoor cat thinks wheat grass is the best treat ever; she doesn't want catnip or canned food for a treat but wheat grass is always welcome.

One thing I didn't see on any of the lists is Sansievera aka mother in law's tongue. I had a rabbit that took a chomp out of one and died a day later. The sapoins (natural soap) caused frothing of the mouth.

According to the ASPCA, it's best to avoid feeding your rabbit iceberg lettuce but the following greens are healthy foods you can feed rabbits: romaine and leaf lettuces, parsley, cilantro, collard greens and dandelion greens.
