The edible garden vegetable (Asparagus officinalis) is a different plant from the ornamental houseplant known as "asparagus fern" (Asparagus densiflorus/setaceus), which is genuinely toxic to cats — its berries can cause vomiting, abdominal pain, and diarrhea, and repeated skin contact with the plant can trigger an allergic reaction. The vegetable spears themselves don't carry that risk, but it's worth not confusing the two.
Cook until tender rather than serving raw, since raw stalks are fibrous and harder to chew safely; cut into small pieces and serve plain.
No. The vegetable you cook and eat (Asparagus officinalis) is a different plant from ornamental asparagus fern (Asparagus densiflorus or setaceus), which is toxic to cats. Keep cats away from the fluffy houseplant version, even though a small amount of cooked asparagus spear is fine.
Raw asparagus is tough and fibrous. A small piece of tender, plain, cooked tip is the safer form, and any seasoning, butter, or garlic makes it unsuitable.
