Plant safety for cats
Is asparagus fern toxic to cats?
MildListed toxic to cats by ASPCA
Yes — asparagus fern is mildly toxic to cats: its red berries can cause vomiting, belly pain or diarrhoea, and repeated contact can irritate the skin. It isn't a real fern.
Why mild: Its berries upset the stomach; repeated contact irritates the skin. Not a true fern.
- Name
- Asparagus fernalso Plumosa fern, Foxtail fern, Lace fern
- Botanical name
- Asparagus setaceus and A. densiflorus 'Sprengeri' · Asparagaceae
Toxic parts
The berries especially; the sap irritates skin.
What's in it
Sapogenins.
How to recognise it
- Feathery, needle-like 'leaves' on thin stems
- Small thorns
- Red berries ('Sprengeri')
Look-alikes and name traps
Not a fern — real ferns like Boston fern are non-toxic. ASPCA lists 'shatavari' as an alias, but the Ayurvedic shatavari (Asparagus racemosus) is a different species that hasn't been assessed.
Symptoms to watch for
- Vomiting, belly pain or diarrhoea (after berries)
- Skin irritation after repeated contact
What to do
Usually settles on its own — but keep an eye on your cat.
- Take the plant away and note how much was chewed.
- Call your vet if vomiting or diarrhoea keeps going, your cat stops eating, or seems weak or wobbly.
- Don't make your cat vomit at home unless a vet tells you to.
Where Indian cats meet it
Hanging baskets, balcony pots and bouquet filler.
Cat-safe swap: Boston fern — listed non-toxic.
