Birds of Prey (2020)

In the scene where the actress walks into a pet store and sees a pig and hyena in their cages, prior to shooting, the animals were loaded, one by one, into their enclosures. There was a vulture on a wood perch; a pig was housed in a wire cage; a python and lizard in a tank; a dog and cat also in cages; a capuchin monkey in wire cage; a parrot with a perch; and a fox.

When we see actress in her apartment with her pet hyena on the ground, the set was inside a private training facility. The hyena was kept inside its holding pen and was fed his regular evening diet by his trainers. He was given long breaks without crew near him between being recording takes.

When we see her in the car with the hyena in the backseat, a dog was used in the scene. They changed the dog to look like a hyena in post.
