Games with Animal Protagonists

From IFWiki

Various games have been written in which the protagonist is an animal (or a fantastic non-humanoid creature). These can pose special challenges for both author and audience, since the ways in which animals interact with their environment is frequently unlike the default behaviour assumed by a standard IF parser. Animal protagonists may sense things in different ways to human ones, but usually more significant is manipulation of objects within the game - a key part of conventional IF, and one that tends to assume opposable thumbs.
