Lime vs. Calamondin Orange: which is safe for cats and dogs?

Lime and Calamondin Orange are frequently compared because they both belong to the Citrus genus and share similar ornamental characteristics. If you are choosing between these two for your home, it is important to know that both plants are considered potentially toxic to pets. While they are not typically fatal in small amounts, both the Lime and the Calamondin Orange contain essential oils and psoralens that can cause significant gastrointestinal distress and skin irritation in both cats and dogs. Because these compounds are present throughout the foliage and fruit, it is best to keep both varieties well out of reach of your curious animal companions.
