I’ve tasted rattlesnake. It doesn’t taste like chicken. More like stringy, boney fish crossed with something else. I would eat it for survival, otherwise I pass.
As for cats I love them too much to eat one. And rats may taste like pumpkin pie, but I won’t eat one because they’re a filthy animal.
G. Gordon Liddy's review of wharf rat: "tasteless and stringy". More.
