You may have already seen this story [1] about the animals in the Zürich Zoo being fed frozen meat and fruit "alternative ice cream" to cool them down. It seems that this isn't so uncommon. 20 Minuten, a free paper that's distributed in Zürich and other Swiss cities, has a great slide show on their web site [2] of animals cooling down, using ice treats and other ways.
Everyone say awwwww... (or in Swiss-German - yööööö)
Go to this page [3] and click on the Bildstrecke starten link below the tiger to see the whole slideshow. Warning: you may faint from the cuteness overload!
(This isn't about human food but I just couldn't pass it up. Besides...the ice treats look kind of good!)
