I can’t remember who I spoke to but someone once told me that avocados were toxic to pets and I never thought to double check the information so whenever I came across someone who asked me about it or when I saw someone trying to feed their pets avocados I’d always tell them they were toxic! But lo and behold that isn’t necessarily the case… sort of!

Persin a natural, oil-soluble fungicide and also the toxic component of avocados is contained within the  leaves, bark, seeds, skin and pits of avocados. It’s virtually harmless to humans unless they suffer from some sort of allergy but can be deadly in certain species of animals. For the record, it is not toxic to both dogs or cats, the only thing pet parents should be concerned about is the rather large pit of the avocado which if swallowed can cause a blockage or obstruction in the pet’s esophagus, stomach or intestinal tract. Other than that if your pet is a fan of avocados they can definitely eat it so long as it is in moderation as it can cause vomiting and diarrhea if given in excess.

As for our other furry friends and large animals caution is to be exercised.


For our birds, signs to look for for persin toxicity include:

– Difficulty breathing

– Weakness

– Unable to perch

– Liver/kidney failure

– Death


For rabbits (and mice) look for signs of:

– Difficulty breathing

– Inflammation of the mammary glands

– Decreased milk production (if your pet is lactating)

– Cardial arrhythmia


For large animals (cows/horses):

– Mastitis

– Decreased milk production (if lactating)

– Gastritis

– Colic

– Sudden death


Now that we’re all in the know let’s spread the good news about avocados!
