4. Philodendron

Philodendrons are cherished for their dramatic leaves and low-maintenance nature, making them a staple in many homes.
Unfortunately, these plants contain toxic compounds that can cause mouth irritation, swelling, and digestive upset in pets and children.
While similar in appearance to Monstera, Philodendrons are generally considered more toxic.
If you love the look but want a safer choice, research Monstera deliciosa, which still requires caution but poses slightly less risk in most households.
