Banana

The banana plant is safe— fruit and foliage alike.

Yes — the banana plant is safe for cats. The ASPCA lists it as "Non-Toxic to Dogs, Non-Toxic to Cats, Non-Toxic to Horses." Both the plant and the fruit are non-toxic.

Banana (Musa acuminata) is a large tropical herb in the family Musaceae — despite its tree-like size, it is technically a giant herbaceous plant, not a tree. As a houseplant or garden specimen, its broad paddle-shaped leaves may tempt a curious cat, but they pose no poisoning risk.

ASPCA Data

According to the ASPCA, banana is listed under plants non-toxic to cats:

Non-Toxic to Dogs, Non-Toxic to Cats, Non-Toxic to Horses.

There are no toxic principles. The plant is completely safe around cats.

Plantain disambiguation — two very different plants

The word "plantain" causes real confusion, so let's be precise:

• Banana plant / cooking-banana "plantain" — this is Musa, the same genus as the dessert banana. It is the plant the ASPCA lists as non-toxic. The starchy cooking banana sold as "plantain" comes from this group.
• Lawn-weed "plantain" — this is Plantago (for example Plantago major), a low broadleaf weed found in lawns and verges. It is an entirely unrelated plant in a different family.

When people ask "is plantain safe for cats?", the answer depends on which plant they mean. This page is about the banana plant (Musa), which is safe. Plantago is a separate question and a separate plant.

Feeding banana to a cat

Banana is a fine occasional treat but not a food:

• Tiny portions. Banana is high in sugar and starch — offer a small mashed or sliced piece, not a chunk.
• No nutritional need. Cats are obligate carnivores; they need meat protein, not fruit. A banana provides nothing essential their diet lacks.
• Watch digestion. Too much can cause loose stool or constipation from the sugar and starch, even though the plant is non-toxic.

Growing a banana plant around cats

Banana plants want bright light, plenty of water in the growing season, rich free-draining soil, and warmth above 15°C. The dramatic leaves make a striking houseplant. Because the plant is non-toxic, there is no safety reason to fence it off — though you may want to discourage chewing simply to protect the foliage.

The bottom line

The banana plant is safe for cats — leaves, stem, and fruit alike — and a banana is a harmless sugary treat in tiny amounts. Just keep the names straight: the safe plant is Musa, not the unrelated weed Plantago. For other safe, cat-friendly greenery, see bromeliad, ponytail palm, and parlor palm.
