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

Lime and Grapefruit are frequently compared by pet owners because both belong to the Citrus genus, leading to questions about whether their aromatic foliage and fruit share the same safety profile. Unfortunately, both Lime and Grapefruit are considered potentially toxic to cats and dogs. Every part of these plants contains essential oils and psoralens that can trigger adverse reactions if ingested or touched. While the specific manifestations of illness can vary slightly between the two species, both plants pose a risk of gastrointestinal distress and skin irritation for your pets. It is best to keep both of these citrus trees safely out of reach of your animals.
