Griffin is performing one of his dastardly experiments on a white cat in an attempt to make her invisible. The experiment, however, is not going well. As he tells Kemp later on, he could not make the cat completely invisible; its claws remained, as well as the tapetum, a pigment from the eye. Nevertheless, he bandages up the cat just as he has done with himself. It soon starts meowing loudly, attracting the attention of the drunken old lady who lives downstairs. The cat belongs to her, and she is convinced that Griffin is performing some kind of vivisection on her poor cat. When Griffin answers the door, she tries to peer past him. The sight of Griffin's room must be very strange to her: it has bare walls, windows without curtains, a truckle bed, and a vibrating gas machine. There is also the hanging stench of chloroform in the air, which Griffin used to knock out the cat in order to prevent her from making noise.
