The difference between cats and dogs, British accents and all, courtesy of Creature Comforts:
In case you're new to Creature Comforts, as I was myself until my brother showed me a side-splitting episode on YouTube (one of several), it's a wonderfully dry and smart clay animation series in which real interviews with everyday people are transposed onto animals in a number of natural, and not so natural, settings. The series was produced by the UK company behind Wallace and Gromit, and began with a short film involving zoo animals:
According to Wikipedia, the short's "dialogue was created by interviewing residents of a housing development, an old folks' home and a family that lived in a local shop." But it's hard to miss the intended inference to the actual conditions of some zoo animals. The rest of the show can't be said to have much to do with animal advocacy directly, but it's just plain funny to watch cartoonish animals talking about off-the-wall human subjects. A number of American episodes were also created in recent years, and you can find out more about them here.
