My Losers head-canon insists that they are shifters/weres.

Cougar...well, he's a cougar. Jensen is a sneaky coyote, Aisha is a shifty jackal, Pooch is a definite Doberman, and Clay is a last-minute GSD. I'm still working on a universe, including Max and co. villains, and secondary characters (Roque, Jolene + kids, and Jensen's sister and niece). STAY TUUUUUNED~
