Wenisrubber, I hope that your gerbil is able to recover.
I have been following your thread because my gerbil Chocolate had a stroke last Friday and I did a lot of research on it last weekend.
I made sure that she was eating and drinking and was as comfortable as possible. My gerbil was also wobbly and became blind due to her stroke.
Unfortunately she passed away this morning, she was just about 3 years old which is old for a gerbil.
I hope that your gerbil didn't have as severe a stroke as mine did and that she can recover. How old is your gerbil? Hopefully if she is young, she can recover.
Sending get well wishes your way.
