Famed lawyer and President, Abraham Lincoln, kept 4 cats in the White House.
Cats would make good investigators because they can see in the dark.
Cats cannot taste sugar so they would not be distracted from work and research, by chocolate.
Cats are Polydactyl and that certainly sounds like it would help on a case. Of course it might also help to know what it means.
Cats can hear ultrasonic noises which would help in interviewing witnesses. Well, witnesses that whisper.
Cats use their whiskers to determine if they can fit in small spaces. I haven’t figured out if that would be helpful in law unless you might be looking for a law book. Yea, that’s the ticket.
Anyway, these two cats seem ready for some holiday vacation.
