Jerusalem Cherry

Solanum pseudocapsicum

Jerusalem Cherry (Solanum pseudocapsicum), also called Winter Cherry, is a common ornamental houseplant and holiday decoration that is toxic to cats. It belongs to the nightshade family and contains glycoalkaloids — primarily solanine and solasonine — throughout all parts, with the highest concentration in the attractive red or yellow berries.

Important Notes

Toxic compounds: solanine and solasonine (steroidal glycoalkaloids); berries are most concentrated, but leaves and stems also contain toxins

Mechanism: glycoalkaloids inhibit acetylcholinesterase and disrupt cell membranes, causing GI and neurological effects

Symptoms: drooling, vomiting, diarrhea, abdominal pain, lethargy, weakness; more severe ingestion may cause tremors, confusion, or bradycardia

The berries resemble small tomatoes or ornamental peppers and are visually appealing to cats

Keep Jerusalem Cherry out of cat-accessible spaces; contact your vet if berry ingestion occurs
