Is Giant honeysuckle toxic to cats?

Lonicera hildebrandiana

Mildly toxic to cats

Mildly. The ASPCA lists giant honeysuckle as mildly toxic to cats — a chewing cat typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Lonicera hildebrandiana is not individually listed by the ASPCA. As a Lonicera species, its berries may cause mild gastrointestinal irritation in pets (vomiting, diarrhoea) if consumed. The flowers and foliage are not considered severely toxic, but given the plant's size and berry production, keep pets from grazing on it. Contact a vet if significant ingestion occurs.

What to do if your cat ate giant honeysuckle

  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
  5. Bring a leaf or photo of giant honeysuckle to the appointment so it can be treated correctly.
