Animal safety

Cat: safe and risky garden plants

Cats are more sensitive to many plants than dogs. Although they are obligate carnivores, many cats regularly nibble grasses, leaves, or houseplants. Because small amounts of some plants can already be problematic, indoor and garden planting should be chosen carefully.
