Hermione, who has lived with me for some ten years, has become enamored of a polished agate about the size of a shooter marble. She picks it up in her mouth (which seems to be a bit of a strain) and carries it around her cage. I thought at first it annoyed her so I hid it, but she sought it out and carried it over to her food dish. She buries it then digs it up, and sometimes forgets about it for extended periods.
I was awakened this morning by the rattle of her attempting to swim out of the back of her tank with it clutched in her jaws. I returned it to land for her and she's now burying it again after she checked many of the other rocks in the area with a nice bite.
Does she think it's a snail? Does she have OCD? It's certainly too large for her to swallow, and I see no wear or tear on her beak. I'll be perfectly delighted to hear that turtles entertain themselves this way, but am concerned that she has gone berserk in some way.
She started this only this past winter, but the rock has been there for years. Her tank is in my bedroom, and I have been out of town more than in because of illness in the family. Could she be LONELY?
Thanks for any light you might shed,
Kim V.
