Elizabeth, whom prefers to be called Eliza, is a cat who is determined to keep her remaining kitten safe. She goes to great lengths in keeping her kitten alive and isn't afraid to put her own life on the line for her. When her baby was snatched away right in front of her eyes, she attempted to scratch, claw and chase those responsible. In doing so, she injured herself and was covered in blood when she entered the laboratory. She found the living quarters of the laboratory to be atrocious and most certainly did not want her kitten living in such an environment. Prior to the kidnapping incident, she lived a luxurious life, hunting mice for a farmer and being left alone by any potential predators or competitors. To repay her for her hard work, the farmers often shared the milk of their cows with her and Persephone.

Persephone: The only surviving kitten in her entire litter. This, alongside the disappearance of her mate, has made Eliza become very protective of her remaining child. She does not take it well when the scientists decide to steal her baby from her. She becomes so desperate to get her back, that she injures herself and breaks right into the laboratory where Adams and Brielle are being kept.
