Heavy Petting Zoo (known as Eating Lamb on the LP version) is the sixth studio album by the American punk rock band NOFX.

NOFX recorded the album in October 1995 with Ryan Greene at the Razor's Edge studio, San Francisco, a garage described by the band as "a total dive".

[5] The music on Heavy Petting Zoo has been complimented as "melodic", and the album has been favorably compared to the band's 1991 Ribbed LP,[6] but although tracks like "Hobophobic (Scared of Bums)" and "Freedom Lika Shopping Cart" have been lauded for their witty titles, they have also been criticized for being overly cynical.

Songwriter Fat Mike commented that he wrote the song, "cuz I fucking hate the Grateful Dead, but it turns out I had the date wrong.

CMJ New Music Monthly, in their review of the album, described it as the band's "nastiest cover yet..",[13] and in their analysis of NOFX's attitude, the authors of Screaming for Change: Articulating a Unifying Philosophy of Punk Rock state: "..the fact that none of the songs on the record deal with animals, zoos, or even bestiality, supports the assertion that the artwork contains little, if any, significant meaning other than portraying images the band is confident will upset and shock the establishment.
