Is echinopsis safe for cats and dogs?
No — echinopsis is toxic to cats and dogs. Keep it well away from any pet that chews plants; reactions can be significant. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. The San Pedro cactus contains mescaline, a psychoactive alkaloid, plus related alkaloids in its flesh. While Echinopsis pachanoi is not individually listed on the ASPCA database, its documented psychoactive alkaloid content means ingestion can cause vomiting, diarrhea, rapid heart rate, disorientation, and neurological effects in pets. Treat it as toxic, keep it well away from cats and dogs, and contact a vet if ingestion is suspected.
