• Self-anointing is probably the strangest and most unexplainable of all hedgehog behaviors.
  • It is completely normal and causes no harm to your hedgehog.
  • Some references refer to self-anointing as “anting”.
  • This term refers to a similar behavior in birds, where certain species of birds will rub ants onto their bodies in order to apply the formic acid ejected by the ants to its feathers
  • Anting in birds, as with hedgehogs, is a form of self-care.


  • Hedgehogs will lick or chew the object of interest and create foamy saliva or lather which they will then deposit onto various parts of its body.
  • It is not uncommon for new hedgehog owners to think their hedgehog is having a seizure or is vomiting.
  • Vomit tends to be more slimy than frothy and usually is a result from motion sickness.
  • Substances that can provoke self-anointing include chemicals, perspiration, leather, perfume, hand lotion, soaps, traces of food on your hands (especially garlic), and excrement.
  • Hedgehogs that anoint frequently or that anoint with a particularly colorful or smelly substance may need a bath.
  • The color of the anointing froth is dependent on the source of the anointing substance.  For instance: blueberries produce blue froth and a new food will produce the same color froth as the food.

Anointing Process

  • Hedgehogs can self-anoint at a very early age, even before their eyes are fully opened.
  • The first sign that a hedgehog is going to self-anoint is that they will show a fascination with a particular odor or taste.
  • Your hedgehog is likely to chomp its teeth or chew at the substance to create the anointing froth.
  • You may see your hedgehog twist and contort in a variety of funny positions as it spreads this foamy saliva on its body using its surprisingly long tongue.
  • Many hedgehogs become so engrossed with this activity that they become oblivious to anything going on around them!

Reasons for Anointing

  • The reasons hedgehogs self-anoint are still unknown, but it is usually related to a new or pleasant smell.
  • Some people believe anointing is a form of scent camouflage designed to cover up their own scent in the environment for protection.
  • Others believe the hedgehogs like the scent so much that they want it on their body similar to our “perfume”.
  • Hedgehogs are resistant to many toxins and one theory is that hedgehogs spread toxins on their spines as added protection or as a repellant to its enemies.
  • Another possible explanation is that they are trying to remember a particular smell by mixing it with the saliva and then depositing it on the spines.
  • Male hedgehogs tend to anoint more than females, but the reason for this trend is unknown.
  • Light-colored hedgehogs tend to look messier with anointing and anoint more frequently than darker hedgehogs.
  • Many believe the lighter colored hedgehogs are trying to camouflage with their environment more so than the darker hedgehogs.
  • When there isn’t anything new and your hedgehog is accustomed to their surroundings, they may not anoint as much.

  • Hedgehogs may lick and self-anoint with things that could be poisonous to them.
  • Be cautious of houseplants, cleaning chemicals, feces of other animals, etc.

Cleaning After Anointing

  • The foam spittle on the hedgehog quills is not dangerous.
  • Some anointing spots are simply saliva.  It dries clear and doesn’t require removal for the hedgehog to appear normal.
  • It is your discretion if you don’t mind small amounts on the quills and you leave it, or if you prefer to wipe or wash it off.
  • Some anointing material will simply wipe off with a damp paper towel.
  • Never use any type of cleaning was or soap that is not ingestible because your hedgehog may self-anoint with that new smell.
  • Some particularly messy deposits on the quills may require a bath to thoroughly clean off the anointing material.
  • The color of the hedgehog and the substance used to anoint plays a part in dried spittle visibility.
  • Some substances may stain light colored hedgehogs but staining is not typical.
