Cats munch this like crazy! I think it gives them a high! It is also an attractive plant. Sold in a 1.5L bag. Catnip prefers full sun, meaning at least six hours of direct sunlight on most days. Too little light can cause leggy growth with sparse foliage. However, catnip does struggle in extreme heat. So if you live in a hot climate, give your catnip a little shade from the strong afternoon sun
