My pet rat has hair loss and itching. Is it parasites or dermatitis?

It sounds indeed like your rats may be suffering from a mite or louse infection. Treatment usually consists of applying an avermectin such as Revolution or ivermectin available either in pet shops, your vet or over the internet. You can use the Revolution for dogs up to 5 lbs, at a dosage of 0.1 ml/lb of rat (you will need a 1ml syringe to measure out the dose correctly. Of course it would be easier to have the treatment done by your vet after he or she verifies whether this is indeed a mite infection/louse infection. Make sure you remove and destroy all bedding and disinfect all cages and toys.

Hi there! Pablo does look pretty itchy by those pictures. Mites are usually microscopic, so if you can see the bug it may be something different. I have seen many rats with lice. Lice are species specific so they are not likely to affect you. You can bathe him and buy a tiny comb to start picking out the bugs and eggs, but he will also likely need to see a veterinarian for medication to get rid of the infestation. Thorough cleaning of the cage and daily bedding changes will also need to be done. I hope he heals quickly!

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! When I see patients like this the first thing I do is a skin scrape to check for residual parasites like mites (which I suspect here) If none are found, often I will do a culture to make sure no resistant bacteria or fungi (like ringworm-another possibility high in the list) infect the skin, and if so what kind. Thank you for attaching pictures! It is very helpful to us. The "blood" that you are seeing is likely a secretion called porphyrin...it can be released due to stress or illness. I hope this information helps! If you need further assistance or would like a consult please don't hesitate to ask.

He could have mites. A skin scraping should be performed and examined under the microscope. It could also be the beginnings of a growth that your rat is trying to bite or scratch off. I'd recommend an exam to better assess the affected area.

Thank you for using Petco Pet Education Center, formerly Petcoach! I can see that Hades has some hair loss, redness, and scratches on his neck and shoulders. This can be caused by fur mites, a skin infection, or a condition known as ulcerative dermatitis. A vet will be able to take a small sample of fur or skin to determine the cause. In the meantime, I recommend trimming Hade's hind nails to prevent him from scratching and causing trauma and applying SSD (silver sulfadiazene) ointment once daily. I hope this helps!

This is probably due to an allergy, although it could also be infection or mites. First of all, in order to rule out skin parasites, you will need to treat with a high quality flea treatment, then ask the vet to perform a skin scrape - this might reveal an infection or a mite infestation. If all of those came back negative, the next step is to treat the allergy symptomatically and try to discover the cause of the allergy. Three main type of allergies are usually affecting pets: food allergies, flea and parasite related ones and environmental type (allergens coming from trees, pollens, dust etc etc). Some medications can be given by the vet in order to repair any possible skin lesions (like steroids and antibiotics). Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

She could have allergies causing her hair loss and eye discharge. The best thing would be to have your vet take a look at her to determine the exact cause and prescribe medications to treat. She may need an antibiotic, anti-histamine and/or corticosteroid to help.
