The plant's scientific name is Smilax rotundifolia, and it's also known by other names such as greenbrier, catbrier, and roundleaf greenbrier.

The good news is that mulberry bush greenbrier isn't listed as toxic to cats. However, it's crucial to understand that it's not entirely safe either.

In rare cases, cats may experience severe digestive issues, such as obstruction, which may require a trip to the vet. This is because the plant's small thorns can potentially damage the esophagus or throat if ingested in larger amounts or if the cat eats the stems or berries.
