WHS an introduction

Wobbly hedgehog syndrome is a neurodegenerative disease which affects the brain and spinal cord of African pygmy and European hedgehogs.It has been reported that the disease may affect up to 10% of African Pygmy Hedgehogs in the USA. Research has shown that patterns occurr in defined family lines, thereby suggesting this disease is heritable. The first signs of Wobbly Hedgehog Syndrome can appear between the ages of 1 to 36 months. The average age of onset is 18 months and it affects both males and females without bias. Within 18 months of the first signs of the disease, most hedgehogs are paralysed and can no longer move. To date all treatments have proved to be unsucessful in curing this disease or even slowing down its progress.


The symptoms of Wobbly Hedgehog Syndrome may include:

  • falling consistently to one side
  • tremors
  • exopthalmos (bulging eye)
  • scoliosis (abnormal spine curvature)
  • seizures
  • muscle atrophy (muscle wasting)
  • dysphagia (problem with swallowing)
  • wasting
  • ascending paresis (slight or partial paralysis)
  • tetraparesis (paralysis in all four limbs)
  • self-mutilation (rare).

These signs and symptoms are not unique to WHS. They may also be signs of other common hedgehog diseases such degenerative disc disease, brain tumor, or septic meningoencephalitis.

WHS and MS (Multiple Sclerosis)

WHS affects hedgehogs in the same way that MS affects humans, in that it slowly degrades muscle control. The first signs of Wobbly Hedgehog Syndrome is a “wobble” when the hedgehog tries to stand still. In time the animal will lose control of all its muscles from the rear to the front of its body. There is no cure for Wobbly Hedgehog Syndrome. Some treatments for MS in humans have had similar results in hedgehogs. These have included high vitamin E diets. Vitamin E conceals the effects of WHS (as it does MS) but does not slow it down. Over time the hedgehog will form a resistance to vitamin E and the effects of the disease will continue.

The cause or causes of both WHS and MS are unknown.

  4. My hedgehog isnt consitantly wobbly. He’ll be wobbly at one point in the day and fine the next. This has happened every other week. At times he won’t be able to walk or hell be shaking and falling over. Is it wobbly hegehog syndrome?

  5. When my hedgehog digs he slides out his rear legs. Is it WHS? I only saw this when I replaced the bedding to sheets instead of pellets.

    it is because the bedding/something slips your hedgehog.try to walk with a piece of cloth in a slippery ceramic floor.

    I’ve truly enjoyed surfing around your weblog posts. After all I’ll be subscribing to your feed and I’m hoping you write once more soon!

  17. I thought you weren’t going to talk smack, Bill??? Jeesh, you had me fleieng guilty with your post to my blog. NEVERMIND now!My smack talking has been pretty limited up to now pointing out that the game this Friday is for Peoria bragging rights (simply a statement of fact) and asking if the Warriors are ready. I will now observe the FACT that for AGES the Warriors have been a yearly ritual sacrifice to the Knights. Richwoods would have had more competition from their JFL squad. It will be nice to actually have a little bit of a contest this year.Since 1983, the Knights have missed entering the playoffs only 4 times and have two state championships and one state runner-up. The Warriors have had 3 playoff appearances TOTAL 1978, 1986 and 1987 and never got past the 2nd round even then. Which team was the Knight’s big competition for most of those years? Woodruff? (Laughing hysterically). Hardly it was most often PEKIN. Bill, you can start bragging when your team develops a 20 year Midstate dynasty.Regarding my divided loyalties the only time that would become a problem is if Richwoods played Pekin. Now that they’re in separate conferences, that won’t be as frequent an occurrence. In some ways that’s unfortunate Pekin vs. Richwoods was a great football rivalry.I also have good reason for my divided loyalties my daughters are in the Pekin school system and Pekin is my current home, while I grew up in District 150 and went to Richwoods. When they’re not playing each other, I can cheer for both. When they are, I can hope for a good game and enjoy the competition. If my daughters join competitive sports teams, I will certainly always cheer for them.I hope it’s a good game on Friday. My wife & I are planning on going.
