Honeysuckle
Lonicera spp.
Honeysuckle (Lonicera spp.) is a common garden vine or shrub whose berries and, to a lesser extent, leaves contain mildly toxic compounds including saponins and, in some species, cyanogenic glycosides. Cats are unlikely to consume large amounts, but berry ingestion can cause noticeable gastrointestinal upset.
Important Notes
Toxic compounds: saponins and trace cyanogenic glycosides in berries; leaves carry lower concentrations
Mechanism: saponins disrupt the GI lining; cyanogenic compounds may contribute mild systemic effects at higher doses
Symptoms: vomiting, diarrhea, drooling, lethargy; typically mild and self-limiting
Berries are the highest-risk part — the attractive red or black berries may appeal to curious cats
Symptoms are usually mild; contact your vet if your cat ingests a significant number of berries
