Can cats or dogs eat lemons?

Cats: Be careful · Dogs: Be careful — Lemon pulp can be eaten in small quantities. But the bark and other parts of the tree contain essential oils and psoralens, which are toxic to both cats and dogs, according to the ASPCA, which classifies lemons (Citrus aurantifolia) as toxic to pets. Thai people use squeezed lime as an ingredient in almost every meal (somtam, tom yum), so be careful not to allow pets to lick the peel or concentrated lime juice. Avoid giving concentrated lemon peel or juice to cats and dogs. If you eat the peel or experience vomiting, diarrhea, lethargy, take it to the veterinarian.
