No, string of hearts is non-toxic to cats. The trailing vine with heart-shaped leaves is one of the safest hanging plants for cat homes.

Also known as: Rosary Vine, Chain of Hearts, Hearts Entangled · Ceropegia woodii

What to do if your cat eats it

No action needed. Cats may still shred the dangling strands for play — the plant survives nibbling far better than it survives being batted off the shelf.

Common questions

Is it safe like string of pearls?

No — string of pearls is toxic. String of hearts is a completely different genus and is pet-safe; the similar names mislead many owners.

My cat chews the vines constantly — any cumulative harm?

No toxicity accumulates, but heavy grazing thins the plant. A hanging spot the cat cannot bat at keeps both happy.
