Orchids (Orchidaceae) are a wide and diverse family of plants popular for their beautiful and often fragrant flowers. With 880 genera and 26,000 species, orchids are the second largest family of flowering plants (sunflowers are the largest family).
Are orchids toxic to cats?
The ASPCA lists the Phalaenopsis, the most common species of orchid as non-toxic. Also known as moon or moth orchid, Phalaenopsis consists of 70 species.
Cypripedium spp. (lady slipper orchid) is a genus of 58 orchids which is labelled as toxic to humans, causing mild skin irritation. The toxic properties are unknown.
Unfortunately, there is no information on other genera of orchid and their toxicity to cats. As a precaution, we recommend sticking with Phalaenopsis species which come in a wide variety of colours to choose from including white, pink, salmon, purple in one colour or speckled.
Other houseplants non-toxic to cats
While many houseplants are toxic to cats and should be kept out of the home, there are also a number of plants which are non-toxic to cats. The level of toxicity can range from mild and self-limiting to life-threatening (lilies are deadly to cats). Pet owners should always research the toxicity of plants before they bring them into the home.
