Question what does it mean when there head is rocking side to side?
Answer Dear Zoe,
Some rabbits have an odd behavior called "scanning." It seems to be most prevalent in albino rabbits, but no one knows why. It may be an exaggerated motion associated with the normal nystagmus of the eyes.
Nystagmus is the natural, microscopic movement that every vertebrate eye makes constantly--including ours! It's what makes vision possible. As our eyes microscopically change the visual field at this tiny level, constantly (we are not aware of it, and you can't see or feel it), the eye's photoreceptors are constantly stimulated by the ever-changing light hitting them. This is why we can see. Without nystagmus, we would not be able to see.
Some people have suggested that albino rabbit "scanning" (the side to side movement of the head you're seeing) is an "outgrowth" of normal nystagmus--but no one knows for sure.
But the bottom line is that it's a genetic trait that is not harmful, and it's nothing to worry about.
I've lived with companion rabbits for more than 35 years, and consider them members of my family. I can answer any questions about the biology and health of rabbits, from the commonplace to the unusual. But please note:
RULE #1: THE INTERNET IS NOT THE PLACE TO SEEK HELP IN AN EMERGENCY.
If your rabbits is LETHARGIC
If your rabbit is NOT EATING
If your rabbit is PHYSICALLY INJURED (including broken bones)
I have been rescuing and rehabilitating domestic and wild rabbits for about 30 years.
I have written articles for many rabbit rescue publications, as well as for the veterinary journal, Exotic DVM.
I own EtherBun, the internet's largest listserve dedicated to health, care, and behavior of domestic rabbits.
