This moring as we were working in the office we heard the growl of something is not right from the front door. We found Tavi with her hackels up and checking out Mr. Turtle who had found his way to our front door.
Looks rather like a soft shell turtle to me--they are aquatic turtles and can be aggressive (one keeper of pet turtles says his turtle "has a typical soft shell personality--a bit bitey") so tell Tavi she should be glad she has a door between her and Mr. Turtle!
Where I grew up in Louisiana there were turtles all over the place; here in Colorado there don't seem to be any. I miss them.
