Is mamoncillo safe for cats and dogs?
Not entirely — mamoncillo is mildly toxic to cats and dogs. It rarely causes serious harm, but chewing it triggers real discomfort, so keep it 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. Melicoccus bijugatus is not individually listed by the ASPCA, so its pet status is not formally established; treat with caution and verify with a vet. Note that the large hard seeds are a serious choking and obstruction hazard and the unripe fruit is astringent, so keep whole fruit, seeds and foliage away from pets even though ripe pulp is eaten by people.
