Cat herding?

One of the more bizarre dramas in recent months here in the Hub is that of a self-proclaimed "cat breeder" who's been arrested on charges of animal cruelty after authorities discovered frozen cat carcasses in her freezer.

At the end of the article, someone notes that approximately three-quarters of all "animal hoarding" cases involve cats. Why? Is there some particular reason why most of the people who go off the deep end in collecting pets tend to favor cats instead of, say, gerbils or mice or hamsters or chihuahuas or something like that? Is it because cats are "lower maintenance" animals?

Bizarre.
