Calamansi (calamondin) is a small sour citrus fruit (Citrus x microcarpa) that turns from green to orange as it ripens. It is grown on compact trees and sold fresh, frozen as juice cubes, or bottled as concentrate. The flavor is tart and aromatic, closer to a lime-orange blend than a sweet orange.
It is widely used in Southeast Asian cooking for marinades, dipping sauces, noodle dishes, seafood, and beverages. Many recipes mix calamansi with soy sauce, fish sauce, sugar, chili, garlic, or onion. Whole fruits are sometimes sliced with peel for drinks. That leaves essential oils and acidic juice in the final dish.
Citrus peel, leaves, and oils are the main concern for pets, and the pulp is still very acidic. Bottled concentrates can be stronger than fresh juice and may include preservatives or sweeteners. Calamansi trees kept as patio or indoor ornamentals can drop leaves and fruit within reach. Avoid routine feeding and keep peel, leaves, oils, and concentrated juice away from pets.
