My mouse is weak with a neck lump and pale eyes. What's wrong?

Thanks for your question about Tiny, and thank you for the photos - they are very helpful. Based on the location on the mass, and how fast it has come on, I would be concerned that it could be an infection, or potentially a tumor. I would recommend taking Tiny into a veterinarian. They can perform an examination, and can put a needle into the mass, remove some cells, and put the cells under the microscope for evaluation. Depending on what they find, they may have medications that they can prescribe (for example, antibiotics if it is an infection). Please don’t give any human medications to Tiny, as many of them are harmful to our furry friends. I hope that gives you a place to start, and that Tiny feels better soon.

Thanks for reaching out about Yuki and including photos. Lumps such as this can be abscesses or tumors. Each requires a veterinary visit to assess and provide a diagnostic/treatment plan. Unfortunately there is little that can be done from home. Monitor her for appetite and activity. Sometimes, local rescue groups with assist with veterinary but you would have to contact them. Good luck.

I would recommend having Peachy examined by a vet. Mice can develop tumors just like humans, and with the small size of their body, it can be some obviously large very quickly. A vet will do an exam and determine if this is the case. If it is, they can discuss treatment options and help you watch out for signs of decreasing quality of life.

Hello there! I'm sorry to hear that Marvin is having some health troubles. The lip and the leg issue are probably unrelated, but depending on the age of your mouse, several things may be going on. If he's a young dude, I strongly suggest checking the length of his teeth, as overgrown teeth can poke into the lip and cause swelling and abscesses. The lump could still be an abscess even if he's older, and especially if he lives with other mice that may have bitten him. It is also possible that the lump is a cancerous tumor. While the location is uncommon, older mice can develop cancers anywhere. The best thing for him is to visit a vet to determine the cause. They will likely palpate the mass, and may take a small sample of cells from within the mass using a very small needle. These cells may then be examined under the microscope, which may help determine what is causing the mass (bacteria, cancer, etc). Treatment will depend on the cause - he may need antibiotics, or the vet may recommend removal of the mass. Limping in mice is usually caused by injury. Take a look at his foot pad to check for redness or lesions, especially if he's housed on a grate or wire mesh as these can cause pododermatitis (a skin infection of the foot). This should also be evaluated by the vet to determine the cause and to get him some pain medication, if needed. Good luck, and I sure do hope that Marvin the mouse recovers!

Thanks for reaching out about Peanut and including photos. Lethargy is just a general sign of multiple illnesses. A veterinary visit is recommended to assess and provide a diagnostic/treatment plan, even if just palliative. Offering water via a syringe could help combat dehydrate, and likewise, softened/wetted food could give calories. This sounds like a respiratory problem, whether infectious (bacterial, viral), metabolic or heart problems, needs to be determined. Good luck.

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.

Thank you for submitting your question regarding Gilrat. I recommend that he sees a veterinarian. A procedure known as a fine needle aspirate is typically performed when a pet has a mass present. A small needle is used to collect a sample of cells to evaluate under the microscope. This allows the doctor to tell you the type of mass and if treatment is required for him. I hope this information helps!
