The composition of Katy Perry’s Purr was crafted by the Firmenich perfumer house. It opens with top notes of peach, forbidden apple, gardenia, and green bamboo, followed by a heart of jasmine, pink freesia, and Bulgarian rose. The base notes include vanilla orchid, creamy sandalwood, white amber, coconut, and musk.

The bottle is designed in the shape of a cat, with jewel-like eyes and a metallic lavender finish.
