One of the much-discussed objects at the 2009 Biennale di Venezia was Liam Gillick's "Cat," an animatronic creature that talked to German Pavilion visitors in three languages. Cat-lovers found the work adorable--assuming that its realism didn't make them uneasy. (Were any animals harmed during the making of this artwork? We hope not, although the work's taxidermic accuracy might be enough to raise feline hackles.)
