Reposting a question I saw on reddit like a decade ago. My favorite answer I read was, “I’d take my 100 dogs home and live like a king.”
Personally, I have two cats, Sansa and Shere Khan. For both, I could significantly narrow down the options by seeing which cats meowed at me the most. (I swear I didn’t teach them to yell, but here we are.) For both, I could bring in a dog to discern which cats weren’t scared of dogs. For Sansa, I could wait until dinnertime and put down some wet food, then see who hems and haws about eating it despite having screamed for it. That might not be enough to get it down to just one each, but oh well. I could use 5 or 10 more cats.
My dog is missing an ear, so that would make her stand out pretty easily. If the rest of the dogs were also missing an ear, I’d look for the one that was trying to play with the rest of them. Calling her name wouldn’t do any good anyways, since she would be way too distracted by the 99 other dogs.
