Quick answer
ASPCA classifies Origanum majorana as toxic to cats and dogs, and Kew accepts that species identity.
Plant identity and scope
This record is limited to Origanum majorana, the accepted species identified by Kew and ASPCA. It remains separate from the existing Greek Oregano record for Origanum vulgare subsp. hirtum.
Governed aliases: Knotted Marjoram, Pot Marjoram, Sweet Marjoram.
What the evidence supports
The toxic result is limited to Origanum majorana. It is not merged with Greek Oregano or broadened to every Origanum species or herb that shares an oregano-like common name.
Safety classifications come from PawPlants' governed evidence record, not from a retailer or product label.
If exposure may have occurred
Prevent further access, retain a label or clear photo, and contact a veterinarian or animal poison-control service for case-specific advice. Do not induce vomiting unless a veterinary professional directs it.
