Is holly toxic to dogs or cats?
Berries and spiny leaves both cause trouble: vomiting, mouth injury.
Same for cats: GI upset plus mechanical irritation.
Holly delivers a double insult: mildly toxic saponins in the berries and physically spiky leaves that damage the mouth on the way down. Holiday garlands shed berries where floor-level foragers find them. Persistent vomiting is your signal to call.
Signs to watch for
- Vomiting
- Diarrhea
- Drooling
- Lip smacking from spiny leaves
