Is hass avocado safe for cats and dogs?
Avoid for a pet household. Hass Avocado is ASPCA-listed toxic to both cats and dogs; even a small chew can drive a vet visit. Plenty of look-alikes on the non-toxic side of the list — see alternatives below. 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. Avocado (Persea americana) is listed by the ASPCA as toxic, citing the toxic principle persin; it is specifically flagged as toxic to horses (respiratory distress, heart failure, oedema). Persin can cause vomiting and diarrhoea in dogs and cats and is severe or fatal in birds, rabbits and ruminants. Keep leaves, fruit, skin, bark and pits away from all pets and livestock.
