24 Common Plants Poisonous to Pets

Pet owners know that dogs and cats often have a penchant for eating strange things. Cats often gravitate toward plastic or wool, and many a dog will chew on whatever it can get its chops around. And then there are plants. Whether garden plants, houseplants, plants in the wild, or flowers from the florist–plants can provide a tasty and tempting diversion for animals, one that can be at odds with your pet’s health.

In order to prevent poisoning by cut flowers or house plants, avoid placing toxic ones in your home where pets may be able to access them. Or better yet, avoid buying flowers and plants that are known to be toxic. Outside is trickier, especially if your dog or cat has a wide range to roam.

For dogs, the animal science department at Cornell University suggests adding bran flakes to his food or switching her diet to one higher in vegetable fibers to deter cravings for vegetation. The only other thing to do is to watch your dog’s behavior when walking outside, and try to prevent them from munching on vegetation unless you know it is harmless. When you see symptoms such as vomiting, diarrhea, difficult breathing, abnormal urine, salivation, weakness, and any other abnormal condition, take your pet to the veterinarian because he may be poisoned.

You can use this list, which has been compiled using information provided by Cornell University and the ASPCA, as a guide to what plants and flowers to keep your eyes open for. The list is by no means exhaustive, there are a number of other toxic plants, but this covers the top offenders. (For a complete list, visit the ASPCA website.)

Aloe vera
Great for burns, toxic to cats and dogs. Who knew? If you keep an aloe plant on hand for burns, make sure to keep it out of reach for your pets.
Symptoms: Vomiting, depression, diarrhea, anorexia, tremors, change in urine color.

Pretty, common as a garden ornamental, and a very popular potted bulb for the holidays…and toxic to both cats and dogs. Be careful with the bulbs, they contain the most toxins.
Symptoms: Vomiting, depression, diarrhea, abdominal pain, hypersalivation, anorexia, tremors.

I need a list for my pet rabbits. I like to feed them organic things from the vegetation around my house. They love dandelions and their greens and clover. I just have to be careful of pesticides.
