When it comes to choosing indoor plants, the striking appearance of snake plants is definitely one of their biggest selling points. They are gorgeous, with long, narrow leaves that come in an array of different colors and textures. But aside from their looks, snake plants are also extremely easy to care for, making them an excellent choice for anyone who struggles with keeping houseplants alive and well.

If you suspect that your pet has ingested a sago palm, seek veterinary care immediately. Sago palms are not worth risking your pet’s life!

Peace lily is a beautiful, elegant plant that has long been a popular choice for indoor gardens. However, peace lilies are not as innocent as they appear. While they are not technically poisonous, they contain a compound that can be extremely bothersome to pets, children, and even adults if consumed. 

Even the pollen from the spadix can cause oral irritation if licked off fur and paws. The culprit is the presence of calcium oxalate crystals. These crystals can cause burning and swelling of the mouth and throat, difficulty swallowing and vomiting. 

In severe cases, they can even lead to respiratory distress. So while pa peace lily may add a touch of beauty to your home, be sure to keep them out of reach of curious children and pets.

Spider plants are common houseplants that are known for being hard to kill. According to the ASPCA, they’re also non-toxic to dogs, cats, and humans. However, just because they’re not toxic doesn’t mean they’re safe for your pup to munch on. 

Spider plants contain insoluble calcium oxalates, which can cause vomiting and other side effects if ingested in large quantities. So, if you suspect your dog has eaten a spider plant, it’s best to call your vet for further guidance.

7.- Rubber Plant (Peperomia)

However, while most Ficus plants are perfectly safe for cats and dogs alike, this particular variety contains irritating sap that can cause serious skin irritation if it comes into contact with your pet’s skin. 

In addition, if your animal chews on any part of the rubber tree plant, they could experience stomach cramps, nausea, and more serious symptoms associated with poisoning.
