Is Lantana toxic to cats?

Yes — lantana is toxic to cats according to the ASPCA. Keep it well away from any cat that chews plants; reactions can be significant. The ASPCA lists Lantana camara as toxic to dogs, cats, and horses. The toxic principles are pentacyclic triterpenoids (lantadenes); ingestion can cause vomiting, diarrhoea, labored breathing, and weakness, with liver failure more common in grazing livestock. The unripe green berries are considered the most dangerous part — keep pets and children away.

The unripe green berries are considered the most dangerous part — keep pets and children away. Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your cat has had access to lantana.

Stay calm. Remove any plant from your cat's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice; a leaf or photo helps the vet treat it correctly.

The ASPCA classification Growli uses applies to both cats and dogs: Lantana is toxic to dogs as well. See the full lantana pet-safety guide for both species.
