Is Hawthorn safe for cats?
Crataegus species
Hawthorn is a genus of shrubs and trees in the rose family, widely recognized for their clusters of small, berry-like fruits known as haws. While generally considered safe for pets, the fibrous nature of the plant material can occasionally cause mild digestive discomfort if consumed in large quantities.

Safety status
What this means for your cat
Cats are safe around Hawthorn — the ASPCA lists Crataegus species as non-toxic to cats. An outdoor cat passing under a Hawthorn faces a thorn-injury risk before any toxicity risk; the leaves, flowers, and berries themselves carry no listed toxic principle.

If a pet has chewed or swallowed plant material and is showing symptoms, contact a veterinarian or poison resource immediately. This product is for structured reference, not diagnosis.
