Keep Your Pets Away From These Poisonous Plants!
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.

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.

Common Signs of Toxicity
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.

What some dog owners may not know is that there are some plants and flowers that are dangerous to our furry family members. It is better to do some research about our garden and plants to prevent dogs from getting poisoned. Also, train your dogs not to eat anything else. In the worst case, call your vet once your dog got poisoned.
Can Guinea pigs eat wild honey suckles? I have some wild ones growing next to the front of my house. I was just wondering but if it is toxic to them then I will not give them any.
Are any nuts safe for pets? I dropped a few peanuts on the floor the other day while cooking; of course with 4 cats in the house those quickly became hockey pucks! I know some dogs love peanut butter; are there any other "pet safe" nuts?
In general, it is good to keep in mind that certain pets may develop allergies, even though a food may be safe overall for an animal species. As to nuts, the ASPCA especially lists macadamia nuts as not good for dogs, as it can cause weakness, tremors, vomiting, hyperthermia, etc. within 12 hours; it isn’t clear if it affects cats, but better to stay away. Black walnuts can also be especially toxic, at least to dogs. Nuts in general are not good for dogs and cats due to high content of oil and fats; the high fat can potentially cause vomiting and diarrhea, or sometimes pancreatitis, or just cause an upset digestive system, as it is not easy for the animal to process the fat. Avoid any moldy nuts or any salted nuts. As for peanut butter, if you do feed it to your pet, be sure that it does not contain xylitol, which is a sweetener that can be toxic to pets. So are there any nuts that cats and dogs can eat? It really depends on the amount and the nut, as well as the animal species and the individual pet. Overall, it’s best to stay away from feeding any nut to a cat or dog; some of them are not toxic, but they can cause stomach upset, or allergies (depending on the pet), or even be a choking hazard. For best advice, we’d recommend consulting with a vet to be extra sure before feeding a nut to Fluffy or Fido. Hope this helps!
A good rule of thumb is, if it comes from a bulb/tuber, it's toxic, especially to cats. Doesn't matter if we're talking daffodils or garlic, lilies or vidalias, iris or turmeric--pretty much every bulb or tuber-based plant contains compounds that are lethal to pets, even in small amounts.
Some of these plants--foxglove, belladonna, Jimson, castor beans, etc.--are also extremely toxic to humans. And since we know human babies are just as likely as our furbabies to see if something's edible by eating it, keep these plants OUT of your home and garden. It's simply not worth the risk!
A few years ago I bought a Norfolk Pine in a pot to have as an indoor Christmas tree. My cat began chewing on it and within days was very ill and almost died. Beware!
Thanks for bringing this to our attention, Sally. The Norfolk pine is also known as Australian pine, House pine, and Norfolk Island pine all under the same Scientific Name: Araucaria heterophylla and in the Family: Araucariaceae. You’ll get no argument from us but for the record the ASPCA claims that this plant is non-toxic to both cats and dogs.
Happy to hear that your cat recovered!
Can Guinea Pigs safely eat the flowers on Chickweed,or is it poisonous to them?
Yes, chickweed is fine for guinea pigs. In fact, it’s quite a tasty treat! To be positive of what’s best for guinea pigs, check with the humane society.
I live where there are lots of pine and cedar trees my dog like to chew on pinecones and small twigs that fall from the trees he does not swallow it he chews off pieces and spits it out. Is this a harmful habit?
