There are differing opinions regarding whether pothos is poisonous to cats. Some sources indicate that pothos belongs to the Araceae family, and most plants in this family are poisonous, including pothos, which has some toxicity. The toxicity is concentrated in its sap; if a person accidentally ingests or comes into contact with the sap, they will be poisoned.

For cats, pothos is also mildly toxic. If a cat accidentally ingests it, it may experience adverse reactions such as diarrhea, vomiting, drooling, and difficulty swallowing. Other sources indicate that pothos is safe for cats because it does not have a toxic effect on them, and it is not included in the list of toxic plants published by the Pet Poison Control Center (ASPCA) in the United States.
