A cat-safe choice
Basil is on the ASPCA's non-toxic list for cats, which makes it a good pick for a home with a curious cat.
Still worth knowing
The ASPCA notes that eating any plant material can cause vomiting and stomach upset in cats, so non-toxic doesn't mean edible. If your cat loves to chew greenery, a pot of cat grass gives it something safe to nibble.
Before you bring a plant home, check the label for its scientific name: common names overlap, and a plant sold as one thing can be a different species.

Plants to keep away from cats
If you are shopping for plants or flowers, these are the ones that can be deadly for cats. True lilies and daylilies cause kidney failure, and even pollen or vase water is enough: easter lily, tiger lily, daylily, stargazer lily, asiatic lily, oriental lily, lily of the valley. Check every bouquet before it comes into the house. See the lily guide and the full plant list.
