Is sunflower toxic to dogs or cats?
Non-toxic, seeds and all (unsalted, shelled).
Non-toxic to cats.
Sunflowers are cheerfully non-toxic for dogs and cats, from petals to leaves. Plain shelled seeds are even a reasonable treat in moderation; salted snack seeds and sharp shells are the only caveats. A pet-safe way to fill a sunny border.
Signs to watch for
- Whole seed shells: mild GI irritation
