Henry the gerbil

[Toni.R]

Hello,         I have noticed recently that when Henry, my white gerbil, stands up, on her back legs, to listen or look for a moment, as they do, she tends to slowly lean to one side. the trouble is that they never stand still like that long enough to really observe them. I'm not sure what this might mean, maybe something to do with her hearing ? Also, I brought them (Minah&Henry) one of those see-through balls that they can run around the room in. Minah loves it and goes crashing around the house in it (under my strict supervision of course!) but when I put Henry in it she tried to run but couldn't get the motion right and kept getting her feet caught in the little gaps. I put her in it on a few more occasions to see if she needed a little more time to get used to it, but she just can't seem to run properly in it! Anyone have any ideas, or does it sound familiar ?      Thanks.                 Toni                                             ***********
