Tama is a blue-grey furred British Shorthair cat with honey-gold eyes whose most defining characteristic is a gaping hole in its throat caused by the Arrow.
Tama is stubborn, sticking to his territory in the cellar when Shinobu Kawajiri attempts to chase him out. After he is killed, he shows a desire for revenge and attacks Shinobu when he sees her in the garden. He is friendly toward Kira until Kira himself deems the newly resurrected Stray Cat a threat. However, he is able to easily forgive Kira, and allies himself with him. Tama is shown to get along well with Okuyasu's father after Kira's death.
Stray Cat allowed Tama to resurrect himself into a sentient plant that retains Tama's intellect and personality. It also allowed him to manipulate the surrounding air and form air bubbles to shoot at enemies.
Tama was once a normal cat that was hit with an Arrow while peacefully lazing about by a tree. He takes refuge in the cellar of the Kawajiri household where he is killed by a broken glass bottle when Shinobu Kawajiri tries to chase him out. After being buried in their garden, his dormant Stand ability brings him back to life as a cat-like plant named Stray Cat.
Araki states he based Tama/Stray Cat off of his grandfather's cat named Chako. As a child, they both doted on it but Chako scratched Araki when he ignored it one day. Araki has since been suspicious of cats as a result.
