Is false shamrock safe for cats and dogs?

Not entirely — false shamrock is mildly toxic to cats and dogs. It rarely causes serious harm, but chewing it triggers real discomfort, so it is best kept out of a pet's reach. 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. ASPCA lists Oxalis as toxic to cats, dogs, and horses due to soluble oxalates. Large ingestions can cause kidney issues; small nibbles cause mild GI upset.
