30 poisonous plants to dogs and cats include the Angel TrumpetFind below my list of garden plants and house plants that are toxic and poisonous to dogs  and cats, and at the very least will make them sick.

We all have plants in our house and yard that are poisonous to our pets – dogs and cats alike. Most often, we aren’t even aware specific plants are toxic to our pets. A few years ago, I spent a good sum of money buying and planting a large assortment of Angel Trumpet plants in my front yard.

It wasn’t until ‘after’ they were in the ground for a few weeks- I learned by reading online that Trumpet plants and vines were not only poisonous to dogs, but also caused paralysis to humans if certain area of the plants were handled. So, I ended up digging up all my beautiful Trumpet plants and putting them in the yard waste recycle bin. Ugh!

There are over 700 plants having the potential to be poisonous or toxic to dogs and cats. If you have a pet that’s a couch potato and not a big explorer – then having these plants in and around your home probably isn’t going to be an issue. However, if you bring a new pet into your home, or your pet is a curiosity hound – just be aware the danger is there for potential poisoning.

 

If you suspect that your pet has been poisoned, contact the American Society for the Prevention of Cruelty to Animals (ASPCA) Poison Control Center at 1-888-426-4435. This is a 24 hour a day hotline. (In some cases a consultation fee may be charged to your credit card.)
