It certainly could be, Joan. Many varieties in the Amaryllidaceae family, including Hippeastrum spp. commonly known as amaryllis), contain potentially irritating substances such as lycorine. The bulb, or rhizome, is usually considered to be the most toxic, but other parts can also possibly produce intense gastrointestinal irritation, depression, drooling (hypersalivation), loss of appetite and tremors, if eaten in large quantities. Based on this, we do advise keeping these plants out of the reach of pets.
