Common Plants That Are Toxic to Cats – What Every Owner Needs to Know
Cats are naturally curious creatures, and many love to nibble on houseplants and garden greenery. However, some plants can be highly toxic to cats, leading to serious health problems if ingested. As a responsible cat owner, it’s essential to know which plants to avoid and what to do if your cat eats something harmful. In this guide, we’ll explore the most common toxic plants, their effects, and safer alternatives.
Why Are Some Plants Dangerous for Cats?
Cats have a different metabolism than humans and dogs, making them more sensitive to certain toxins found in plants. Even a small nibble on a toxic plant can lead to vomiting, diarrhea, drooling, lethargy, or more severe symptoms such as organ failure. Some plants are irritants, causing mild discomfort, while others can be deadly.
