Rats with tails - squirrels

Although the dozen or so fox squirrels that inhabit the Phactors' estate are big, handsome, fat critters, they are terribly destructive, greedy sods, chewing on everything (bonsai trees!), digging everywhere, eating anything edible, so from time to time the Phactor has tended to be a might critical, even hostile, or derogatory ("rats with fluffy tails"), but this fossil find indicates it could be worse! Saber-toothed squirrels! Wouldn't want one of the kitty girls getting their paws on this critter!
