There's not much we know about this eBay listing for a 1965 book called Sex Life of a Single Cat...
It appears to be an office comedy or drama, taking place at a cat nip company.
A cat applies for a job and is asked whether she (or he) has done the sex. Not weird at all.
Not really sure I get this joke either, but it's definitely a dirty one.
This kitty definitely has a sexual harassment lawsuit on her paws. Time to call FR (Feline Resources).
Apparently, either a character wins first place for something, or this book got an award. The latter seems...unlikely.
