 The chase scene at the end of the game , in which Don pursues Adrienne throughout the entire mansion , took a full week to film . Homb wore a prosthesis on his face to simulate wounds from Adrienne pouring acid on him . Only one prosthesis was available , and it was in such bad shape by the end of filming that Williams said " we were essentially holding it in place with the proverbial wire and bailing wax " . Several scenes in Phantasmagoria involved animals , including a Doberman Pinscher , two cats , a beagle and several rats . Sierra commissioned Dave Macmillian and other Hollywood animal handlers from the company Worldwide Movie Animals to handle the animals . Two cats were required to portray Adrienne 's pet Spaz because the cats were temperamental and each would have moments when they would not perform . The Doberman Pinscher simply barked behind a fence during his scene , and was trained to bark on command using different hand signals . The scene with the rats simply involved them running along a wall in a basement , which they were trained with to do using food . Some objects were borrowed by a museum operated by the Fresno Flats Historical Society and used as props in the game . The society was thanked in the credits as a result . Ultimately , all of the scenes filmed for Phantasmagoria were used in the final game . While some were edited for length and pacing , none were cut altogether .
