⚠️ Asparagus Fern (Critical)
Asparagus fern (the ornamental plant) is toxic to cats and must be avoided. According to the ASPCA and Pet Poison Helpline:- Toxic - Contains sapogenins, which can cause vomiting, diarrhea, and skin irritation
- Different from edible asparagus - The ornamental plant is not the same as the vegetable

Asparagus spears can be a choking hazard if not cut into very small pieces. Always cut into bite-sized pieces appropriate for your cat's size.Safe Ways to Feed Asparagus to Cats
