The Battle over Trust Funds for Pets

In Rich Bitch, an Annals of the Law piece in The New Yorker, Jeffrey Toobin uses Leona Helmsley and Trouble to discuss inheritances for pets:

[T]he clear motivation underlying Leona Helmsley’s will—her desire to pass her wealth on to dogs—is more common than might be expected. Pet-lovers (many of whom now prefer the term “animal companion”) have engineered a quiet revolution in the law to allow, in effect, nonhumans to inherit and spend money. It is becoming routine for dogs to receive cash and real estate in the form of trusts, and there is already at least one major foundation devoted to helping dogs.

Leona's love for Trouble was matched, it seems, only by her disdain for almost all members of the human race. Could this be true of others who leave wealth to those who woof?
