Is It Normal for Guinea Pigs to Scratch Themselves?

Yes, it is normal to scratch themselves after grooming or waking up from a good nap. The guinea pigs might suffer from itching from the hay, bedding, or different creatures around them who have mites or lice. 

However, make sure that it’s not normal if they scratch themselves frequently with hair fall. 

Normal Scratching Behavior in Guinea Pigs

Guinea pigs are small chubby animals that show certain behavior to express themselves. Guinea pigs scratch themselves, and this scratching is of two types: normal and frequent scratching. 

Normal scratching most commonly occurs in guinea pigs when they wake up from a good long sleep or at the time of grooming. Owners Have nothing to worry about. 

This type of scratching does not cause pain if there is no infection. And can be identified if the guinea pig has no hair loss, redness on the skin, or even bleeding due to scratching. 

Guinea pigs have sensitive skin and tend to care more than other animals. They love itching themselves sometimes or when they contact other animals. Mostly normal itching occurs through their mouth or by their hind legs. 

Itching can also occur due to mild allergic reactions or dust, and you can treat it by changing the bedding or the food. The most effective bedding for the guinea pigs is fleece bedding which is soft and very comfortable. 

Following are some ways for your little guinea pigs to stop itching themselves:

  • First, keep its cage neat and clean.
  • Change the bedding.
  • If other guinea pigs have mites, keep them away from healthy ones.
  • A proper diet.

Abnormal Scratching Behavior in guinea pigs:

Abnormal Scratching Behavior in guinea pigs

When scratching the guinea pigs becomes frequent, it is important to consult a vet. Serious scratching occurs through fungal infections, mites, hay mites, lice, dry skin , or severe allergic reactions. It can lead to death and seizure if you do not treat it. 

The lice and mites are so small that the naked eye cannot notice them. The vet can diagnose them through a special kind of instrument. 

The other reason for severe scratching is a fungal infection, which occurs due to dirty surroundings, so keeping the cage clean can help it. This treatment takes about 5 to 6 weeks. 

Abnormal scratching can cause hair loss, bleeding in the scratching areas, redness and can be treated by a special shampoo given by the vet.  

Mites are often found under the pigs’ skin, with eggs laid by the mites taking around 10 months to be diagnosed. Lice are different from mites. These are found running on the skin and are sucking and chewing. The sucking lice are more dangerous than the chewing mice.
