Why is my hamster itching, sleeping more, and showing signs of stress?

Your hamster may be suffering from ectoparasites such as mites or fleas and/or an allergy to the bites. I suggest you take him to a veterinarian for a hands-on exam and diagnosis. The vet can prescribe or treat your hamster with a proper medicine to kill the parasites. There are mite treatments for hamsters available in the pet shops, but I am not sure whether they are effective. You will definitely need to clean and disinfect your hamster's cage, bedding and toys and food and water containers to hopefully prevent the mites from reinfecting your hamster after treatment.

He is probably itchy. Itch in hamsters can be caused by this could be due to an allergy, although it could also be infection or mites. A clinical examination at your local veterinarian is essential to confirm these clinical suspicions and treat appropriately. Some skin tests may be needed to rule out mites and infections.

Hi there! So very sorry to hear about Jasper! I certainly think you're on the right track thinking about mites. This diagnosis however should be confirmed or ruled out by your veterinarian who can scrape the skin for mites and identify them under the microscope. The itchiness from the mites can cause stress and weight loss. Other causes of itchy skin can be sensitivity to any new products in the environment that may be causing itch and irritation. Also, hamsters can develop Cushing's disease, which effects the adrenal glands - tiny glands around the kidneys that control hormone levels. These hormone levels can become disrupted in this disease process and cause thinning skin and weight loss. Either way, I'd bring your little guy in to see his veterinarian, so he can have an exam and some testing done. One of the mites we can see on pets is called a scabies mite, and those are contagious to humans. Therefore I'd have him seen as soon as you can!

This is likely to be due either to a mite infestation or possibly an allergy. Intense itch can cause severe distress in hamsters. A clinical examination at your local veterinarian is essential to confirm these clinical suspicions and treat appropriately.

Poor Olaf! This could be due to an allergy or she could have picked up some type of parasite like lice or mites. I would have your vet look at her to see what is causing the itching. If she itches too much with no resolve she could cause herself to develop a skin infection. I hope this helps and she starts to feel better soon.

There are a number or reasons why Blizzard is scratching himself a lot. It could be allergies such as a contact allergy, but it could also be that he is suffering from dry skin or mites. The only way to know for sure is to have him seen by a vet. The vet can diagnose what is causing his itching and can prescribe a treatment for him. I recommend taking him into the vet first thing on Monday. Best of luck, I hope this helps!

Thank you for using Petco Pet Education Center, formerly Petcoach! There are many reasons for itching and overgrooming including bacterial infections, mite infestations and trauma. Your vet can take some skin samples to determine the exact cause. In the meantime, you can trim your hamsters nails to prevent further self trauma.
