Also called: sweet basil · Thai basil · Saint Joseph's wort · ocimum basilicum · fresh basil · dried basil · basil leaves
Dog
No described toxicity
Described signs
It is not listed as toxic to dogs in the ASPCA plant list. Pesto is a different matter: it contains garlic, and garlic is toxic and has a warning of its own. With a whole pot, what you would expect is vomiting from the sheer volume of leaf, not poisoning.
Cat
No described toxicity
Described signs
It is not listed as toxic to cats in the ASPCA plant list. Pesto is a different matter: it contains garlic, and garlic is toxic. Basil essential oil does not belong here either: it is more serious, and cats are the most sensitive species.
