I heard they are good eating.
You talkin’ about the cat, the rats or the rattlers? or, maybe all three?
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.
