What's causing my male mouse's sudden scabby rash and hair loss?

Thank you for using Boop by Petco! The condition you are describing sounds a lot like ulcerative dermatitis, a condition that is very common in mice, though the cause is unknown. The condition is characterized by very itchy wounds that form crusts, but unfortunately the cause is unknown. It may be caused by stress or an autoimmune disorder, but these are merely theories. Fortunately, the wounds often heal on their own - you can trim the hind nails carefully and apply SSD (silver sulfadiazene) ointment to the area twice a day. If the wounds become severe or very deep, you may need to seek veterinary care for pain medication.

Thanks for reaching out. Scratching to the point of bleeding and wounds, is likely fur mites, which are difficult to see with the naked eye. A veterinary visit is recommended to take a skin scraping and examine under the microscope. If positive, both mice need to be treated. Good luck.

Thank you for using Boop by Petco! It is a little difficult to see in the photo, but there is what appears to be a small area of scabbing and hairloss, both of which are patchy on the hip. This can be caused by a skin infection, certain cancers, fungal infections, or skin mites which are very common in hamsters. These mites live within the hair follicles rather than cage surfaces, so cleaning the cage will not get rid of any of the possible causes. Mochi should be seen by a vet who can perform some quick tests on this area of skin to determine the underlying cause and start her on the appropriate treatment. In the meantime, to keep her more comfortable, you can gently trim her nails to keep her from traumatizing herself as she scratches. I hope this helps!

Hi there! Fur mites are relatively common in mice, especially if they are from a pet store. There are other conditions that can cause hair loss and skin lesions, but many times the most damage done is self-inflicted. I strongly suggest trimming little Rosy's rear toenails if you can, especially if the skin lesion is at a location that she can scratch at (like the back of her neck, or between the shoulder blades). A tiny scissor or a human fingernail trimmer is good for this. In albino mice, you should be able to see the small, pink vein in the nail - avoid cutting past this. If you do accidentally nick a toenail, don't worry - a small bit of corn starch should stop this up. In a pinch, scratching a bleeding nail on a bar of soap can help, too. Usually, simply putting pressure on it for a minute or so is enough to stop the bleeding, too. Once her nails are trimmed, I suggest cleaning up any skin lesions with a mild soap and water solution, then placing a protective ointment (like the an

This could be local infection or trauma caused by a cagemate. Separate him if you can and see if the hair loss resolves. Use as dust free a bedding as possible to prevent sneezing. Monitor for lethargy, nasal discharge or decreased appetite. He may need to be physically examined by your veterinarian to diagnose respiratory infection and have antibiotics dispensed.

First of all, Maizy looks more like a rat in the picture, unless she is an extremely large mouse. the lesions looks like a wound at the moment, but if it started as a lump it could be an abscess or a tumor. you will have to take her to an exotic vet specialist to get this checked and treated, if it is an infection she will need a course of antibiotics in order to heal properly.

Hi, thanks for using Boop by Petco! Poor Mouse! Thanks for the pictures! The most common reason for an itchy red rash in that location is allergies from the environment or from food. It isn't an emergency so he can be seen when ever you can get him in and your Vet is free. Steroids and antibiotics tend to clear it up as long as the underlying cause is found. Sometimes changing the food protein really can help if it is a food allergy. I wish you and Mouse the best!

Hello! I'm sorry to hear that Mickey is having some skin problems. Skin issues are not all that uncommon in mice, the location you mention (the ears) is common for irritated skin. The eye problem probably did stem from him scratching at his ears - sometimes they accidentally scratch the sensitive tissue around the eyelids and cause irritation unwittingly. The best thing you can do for Mickey is to trim his toenails - many skin and eye issues in mice are self-inflicted, and having short nails keeps them from being able to cause further damage. A small human nail clipper works well for this purpose, but if you are uncomfortable with restraining your mouse safely, a vet's office can do it for you. They may also be able to suggest an ointment for the irritated ear tissue. Additionally, they can check for parasites that might be causing him to scratch - this is unlikely, but worth ruling out. In the meantime, to protect the eye, a plain artificial tears ointment that you can get from the d

This looks extremely painful and could be due to trauma, infection (fungal, bacterial or parasites) or even metabolic disease. Your veterinarian will be able to perform tests to properly diagnose Alexander and prescribe appropriate treatment.

Monitor for redness, bleeding or excessive scratching. Clean and sanitize the cage and cage furniture. Discard anything that cannot be sanitized. If the bald patch increases in size or if she develops any of the above symptoms, have her examined by your veterinarian or a vet experienced in treating pocket pets to diagnose illness or injury. If she has cagemates, monitor for barbering (over grooming by other mice).
