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
