So the other day Jett passed over the bridge. I let Blanche and Zelda see her after she had passed as some think that rats can understand what it means when a cage mate dies. Anyway, today and last night I see both of my girls in the silent spinner wheel. Blanche would never go near it; and Zelda would use it years ago when she was a baby but never since then. Now they are sitting in it, sometimes together, sometimes alone. Another oddity is that Jett had a sleeping spot in a shoe box. Now Blanche hasn't slept in that spot, but she has jumped in it a few times today and looked around, then she hops back out. What do you think, are they missing Jett?
