Potion of Animal Friendship is a uncommon potion in D&D 5e. It does not require attunement.
Potion, uncommon
When you drink this potion, you can cast the animal friendship spell (save DC 13) for 1 hour at will. Agitating this muddy liquid brings little bits into view: a fish scale, a hummingbird tongue, a cat claw, or a squirrel hair.
