We at PETA very much love the animal companions who share our homes, but we believe that it would have been in the animals’ best interests if the institution of “pet keeping”—i.e., breeding animals to be kept and regarded as “pets”—never existed. The international pastime of domesticating animals has created an overpopulation crisis; as a result, millions of unwanted animals are destroyed every year as “surplus.”

    This selfish desire to possess animals and receive love from them causes immeasurable suffering, which results from manipulating their breeding, selling or giving them away casually, and depriving them of the opportunity to engage in their natural behavior. They are restricted to human homes, where they must obey commands and can only eat, drink, and even urinate when humans allow them to.

It's interesting though -- all of this is easily searchable online. If you really read into their own literature and statements of people behind PETA, you'll find some real radical takes. People hear all this, but still choose to disbelieve and not do their own research. They don't hide anything. They're open about all of it.
