Is Heartleaf Hornbeam toxic to cats?

No — heartleaf hornbeam is listed by the ASPCA as non-toxic to cats. It is a sensible choice for a home with a cat; a curious nibble will not poison them, though no plant is meant to be eaten. Carpinus cordata is not listed as toxic by the ASPCA and no toxic principles are documented for the genus Carpinus in major veterinary toxicology sources. Considered safe in gardens with pets. As with any plant, ingestion of large amounts could theoretically cause mild gastrointestinal upset, but no specific toxicity is recorded.

Yes — the ASPCA lists heartleaf hornbeam as non-toxic to cats and dogs. A cat that chews a large amount of any foliage can still get a mild, brief stomach upset, so discourage grazing, but it will not be poisoned.

The ASPCA classification Growli uses applies to both cats and dogs: Heartleaf Hornbeam is non-toxic to dogs as well. See the full heartleaf hornbeam pet-safety guide for both species.
