I don't know about Ratbag, a cat, and beer.
I do remember meeting a dog who at a camping meet licked up the puddle thru-out the day under the beer keg. He was a very mellow and sleepy dog after and when he'd slept it off went back for more.

One of my Mom's cats has decided that any spinach on Mom's plate will be shared. He gets his own bowl on the floor now.
There is a vid of a cat eating a cob of corn... Quality grass human.
