Is wisteria toxic to dogs or cats?
The seeds and pods can cause severe vomiting; a few seeds matter.
Risky, though cats rarely chew the pods.
Wisteria's seed pods look like pea pods and drop where dogs forage; the seeds contain lectins that cause severe, persistent vomiting. A couple of seeds are enough to make a dog seriously ill. Rake up fallen pods in season.
Signs to watch for
- Severe vomiting
- Diarrhea
- Dehydration
- Depression
