Snake Plant / Mother-in-Law’s Tongue
Sansevieria spp.
Snake Plant (Sansevieria spp., reclassified as Dracaena trifasciata), also known as Mother-in-Law’s Tongue, is a popular low-maintenance houseplant that is mildly toxic to cats. Like other Dracaena species, it contains steroidal saponins throughout its leaves that cause gastrointestinal upset when ingested.
Important Notes
Toxic compounds: steroidal saponins throughout the leaves
Mechanism: saponins disrupt cell membrane integrity and irritate the GI mucosa; cats may show the characteristic dilated pupils (mydriasis) seen with Dracaena saponin exposure
Symptoms: vomiting (sometimes blood-tinged), drooling, loss of appetite, lethargy, dilated pupils
The plant is low-growing and often accessible to cats on the floor — consider relocating to higher shelves
Symptoms are usually mild and self-limiting; consult your vet if vomiting is severe or pupils remain dilated
