Swiss cheese plants placement for Cat Owners

Placing a Rosemary plant next to any houseplants (toxic or nontoxic) that your cats love to chew on is a great way to safeguard your home garden and your pet! Cats hate the Rosemary plant due to its high aromatic scent. Other common ways are by sprinkling cayenne pepper on the plant’s leaves and stems or putting fresh orange/lemon peels in the pot.
