Is common sorrel safe for cats and dogs?
No — common sorrel 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 ASPCA lists Sorrel (and Dock, Rumex) as toxic to cats, dogs, and horses. The toxic principle is soluble calcium oxalates; signs include salivation and tremors, with kidney failure rare in cats and dogs. Large ingestions are the main concern; keep grazing pets away.
