Safety status
What this means for your cat
For cats, purslane (also sold as moss rose) is toxic because of soluble calcium oxalates concentrated in its succulent leaves and stems. ASPCA lists tremors, salivation, muscle weakness, depression, and diarrhea as clinical signs, with kidney failure rare in dogs and cats. Most exposures are mild, but a cat that grazes heavily — especially on stressed, oxalate-rich plants — can become seriously sick.
What to watch for
Most common: drooling/salivation and reduced appetite shortly after chewing the plant. Often: vomiting, diarrhea, and depression (a cat that just lies around and ignores normal cues). Possible: trembling and muscle weakness. Less common but serious: signs of kidney trouble — increased thirst, increased or decreased urination, vomiting that won’t stop — typically only after a large ingestion.
Time window
ASPCA does not list specific timing. Soluble-oxalate signs typically begin within a few hours of ingestion; mild GI signs usually resolve within 24–48 hours, but kidney monitoring may be advised after a large ingestion.
When to call the vet
Call promptly for tremors, persistent vomiting, weakness, or any sign of changes in drinking or urinating. Treat large ingestions as urgent so a vet can monitor kidney values. ASPCA Animal Poison Control: (888) 426-4435.
