Is lonicera caprifolium safe for cats and dogs?
Mildly. The ASPCA flags lonicera caprifolium as mildly toxic to cats and dogs — a chewing pet gets oral irritation and drooling rather than a medical emergency, but it is still worth a high shelf. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. Lonicera caprifolium is not individually listed on the ASPCA toxic or non-toxic plant lists — the genus contains both ASPCA-listed-toxic and unlisted species, so treat it as uncertain and verify with a vet. The red berries and foliage contain saponins that can cause mild gastrointestinal upset (drooling, vomiting, diarrhoea) if eaten. Keep pets and small children away from the fruit.
| Pet | Toxic? | Per ASPCA |

| Cats | Yes (mild) | Mildly toxic to pets |
