String of Turtles (the trailing peperomia Peperomia prostrata) is listed as non-toxic to cats by ASPCA Poison Control. That classification does not mean a cat can eat the plant without consequences: ASPCA cautions that any plant material may cause vomiting or gastrointestinal upset in cats. If your cat is ill after chewing it, or you are not certain which plant was eaten, contact a veterinarian. ASPCA Poison Control lists (888) 426-4435; a consultation fee may apply.

The most important practical issue is identification. North Carolina State University Extension identifies String of Turtles as Peperomia prostrata, while the ASPCA record spells the listed scientific name Peperomia prostata. Check the plant tag and keep a photograph or sample available if you need professional advice.

Is String of Turtles toxic to cats?

According to the ASPCA Poison Control record for Trailing Peperomia, String of Turtles is classified as non-toxic to cats and dogs. The record does not identify a toxic principle, dangerous dose, expected symptom timeline, or plant-specific treatment because those details are not provided for this entry.

“Non-toxic” is therefore a poisoning classification, not permission for a cat to eat the plant. ASPCA’s general guidance on its plant database says that consuming any plant material can cause vomiting and gastrointestinal upset in dogs and cats, including plants listed as non-toxic. A cat that takes a few bites may have no problem, but you cannot use the database label to predict exactly how an individual cat will react.

How do I identify a String of Turtles plant correctly?

Confirm the scientific name before making a safety decision. NC State Extension describes String of Turtles as Peperomia prostrata, a delicate trailing vine with tiny, round, succulent green leaves marbled in darker green; some plants have white or silver marbling. Its trailing habit and turtle-shell-like leaf pattern are useful clues, but appearance alone should not replace identification when a pet may have ingested an uncertain plant.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

The spelling difference matters. NC State uses P. prostrata, whereas the ASPCA listing uses P. prostata. Common names can be shared by unrelated plants, and database photographs may not look exactly like every cultivated specimen. Read the nursery tag, pot label, or purchase record and compare the scientific name with the NC State Extension plant profile and the ASPCA record.

If the label is missing or the names do not match, photograph the whole plant, its leaves, and the container. Give those details to your veterinarian or a poison service rather than assuming that a visual resemblance proves the identity.

What could happen if a cat chews String of Turtles?

The evidence supports a limited, careful answer: ASPCA lists the plant as non-toxic, but says any plant material may cause vomiting or gastrointestinal upset. The available plant-specific record does not establish how much a cat would need to eat, how quickly symptoms would begin, or which clinical signs are unique to String of Turtles.

That means you should not rely on an online dose calculation or a predicted waiting period. A cat’s response can also be affected by what else it ate, the amount swallowed, and underlying health issues—questions a veterinary professional can assess when you describe the incident.

Do not confuse normal plant chewing with proof that the plant is safe as food. Even a non-toxic houseplant can irritate the digestive tract, and a different plant growing nearby could have a very different risk profile.

My cat ate String of Turtles—what should I do?

Start with identification and observation, then escalate based on your cat’s condition. Because the plant is listed as non-toxic, a small bite is not automatically an emergency, but illness or uncertainty warrants professional advice.

  1. Move the plant away. Prevent further chewing and keep the pot, plant tag, and any fallen leaves.
  2. Confirm what was eaten. Check whether the plant is labeled Peperomia prostrata (or the spelling used in the ASPCA record, Peperomia prostata). If you cannot confirm the identity, say so clearly when you call.
  3. Record the relevant facts. Note roughly when you noticed the chewing, which part of the plant may be missing, and whether your cat is acting ill. Do not invent an amount or timing if you did not see the event.
  4. Contact a veterinarian if your cat is ill. ASPCA advises contacting a veterinarian or ASPCA Poison Control when a pet is ill or may have ingested a poisonous substance. Call your regular clinic, an emergency veterinary service, or ASPCA Poison Control at (888) 426-4435; a consultation fee may apply.
  5. Follow the professional’s instructions. Have the plant information and photographs ready. The professional can decide whether your cat needs an examination or other care.

The sources used for this article do not support a home treatment, medication, dose threshold, or symptom-onset schedule. Avoid substituting a generic internet remedy for an individualized veterinary assessment.

When should I call a veterinarian or poison service?

Call promptly if your cat seems ill after chewing the plant, if you cannot identify the plant with confidence, or if you suspect another substance was involved. The non-toxic listing applies to the identified trailing peperomia record; it does not clear an unknown plant or a mixed mouthful of leaves.

Tell the clinician that the suspected plant is String of Turtles and provide the scientific name shown on the label. Mention any uncertainty, the possible time of exposure, and anything else the cat could have reached. ASPCA’s record specifically directs owners to veterinary or poison-control help when a pet is ill or may have ingested a poisonous substance.

Do not wait for a particular number of hours based on a database entry: the ASPCA record supplies no plant-specific symptom timeline. Likewise, it does not provide a dose at which symptoms are expected, so a professional—not a guessed threshold—should determine the next step.

What does “non-toxic” mean in the ASPCA listing?

It means ASPCA places Trailing Peperomia in its non-toxic category for cats and dogs. It does not mean the plant is edible, that every cat will remain symptom-free, or that all plants sold under a similar common name share the same classification.

ASPCA also notes that its plant list is not all-inclusive and that individual plants may differ from database photographs. The listing has no plant-specific toxic compound, clinical-sign profile, dose guidance, or treatment protocol. Those omissions are limits of the available record, not evidence that a particular amount is harmless.

How can I prevent a cat from chewing String of Turtles?

Prevention is simpler than trying to identify a mouthful after the fact. Place the plant where your cat cannot reach the vines, leaves, or dropped pieces, and inspect the floor around hanging or trailing containers. Secure the pot so climbing or batting cannot pull it down.

Keep the original label and a current photograph with your household pet records. If you move or propagate the plant, transfer the scientific name to the new container. This prevents a future call from relying on a vague common name.

Check every new plant before bringing it into a cat’s space. A collection can contain several plants with similar trailing forms, while the ASPCA list is not exhaustive. When a plant cannot be identified confidently, keep it inaccessible until a knowledgeable professional confirms it.

How should I explain the risk to everyone in the household?

Use a precise message: “This String of Turtles plant is listed as non-toxic to cats, but any plant material can upset a cat’s stomach. Keep it out of reach, and tell me immediately if the cat chews an unidentified plant or becomes ill.” That wording avoids both extremes—calling the plant poisonous without evidence and treating it as a snack.

Ask children and visitors not to offer leaves to the cat. If a plant is moved for watering, cleaning, or repotting, return it to its inaccessible location and pick up trimmings. Clear communication is especially important in homes with several peperomias or unlabeled cuttings.

What information should I have ready when I call?

Have the plant’s label, a clear photograph, and the source of the plant if known. Write down the scientific name exactly as printed, including whether it says prostrata or prostata. Also note which cat may have chewed it, what you observed, and whether the cat appears ill.

Do not claim certainty about the amount eaten or the time if you did not witness it. “Possibly chewed sometime this afternoon” is more useful than a made-up estimate. If other plants, cleaners, medicines, or foods were accessible, mention them so the veterinarian or poison service can assess the whole exposure rather than one plant in isolation.

What are the key safety facts?

Question Evidence-based answer
Is String of Turtles poisonous to cats? ASPCA lists Trailing Peperomia as non-toxic to cats.
Can chewing still cause a problem? Yes. ASPCA says any plant material may cause vomiting or gastrointestinal upset.
What is the botanical name? NC State identifies String of Turtles as Peperomia prostrata; the ASPCA record spells its listed name Peperomia prostata.
Is there a safe dose or symptom timetable? Not in the reviewed plant-specific record.
Who can assess an ill cat? Your veterinarian, an emergency veterinary service, or ASPCA Poison Control at (888) 426-4435.

Bottom line for cat owners

String of Turtles is classified as non-toxic to cats by ASPCA, but it is still a plant rather than a food. Verify that the plant really is the trailing peperomia described by NC State, prevent further access, and contact a veterinarian if your cat is ill or the plant’s identity is uncertain. The evidence does not justify a dose, a waiting period, or a home-treatment recipe.

Frequently Asked Questions

Can a cat eat String of Turtles regularly if it never gets sick?

No. The ASPCA classification addresses toxicity, not suitability as a regular food. Repeated access also makes accidental confusion with another, unidentified plant more likely, so keep the plant out of reach.

Why do the scientific names on the two records differ?

NC State Extension calls the plant Peperomia prostrata, while the ASPCA record uses Peperomia prostata. Treat the difference as an identification checkpoint: show the exact label and a photograph to a professional if there is any doubt.

Is a String of Turtles cutting safer than a mature plant?

The available sources do not establish different toxicity for cuttings, stems, leaves, or mature plants. Handle every piece as plant material that should be kept away from cats, and seek advice if a cat chews an unidentified cutting.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Does ASPCA’s non-toxic list cover every houseplant sold as String of Turtles?

No. ASPCA says its plant list is not all-inclusive, and common names can be applied inconsistently. Confirm the scientific name rather than relying only on a shop label or a visual match.
