Why does my cat have a skin problem on its back near its tail?

This does not look like mange, however this could be a fungal infection or a bacterial infection or overgrooming in a spot where the cat experiences pain. You should schedule an appointment with a veterinarian for a skin exam. If it is a fungal infection (ringworm) it would be contagious. to other pets as well as humans.

This doesn’t look suspicious for ringworm; however, I would recommend getting this area tested through your vet to confirm. This could be a bacterial infection that requires antibiotics for resolve. I hope that Thor’s skin resolves soon! Best of luck moving forward! Take care.

Ringworm typically presents as lesions on the head and face. This area looks more indicative of a flea allergy or stress related licking. Cats with fleas will often develop an allergy where they start to lick and chew at the area on their lower back. This condition usually requires the cat be treated for the fleas and medication to reduce the itchiness. This could also be compulsive licking or another type of skin infection/allergy. I recommend having her seen by a veterinarian when possible for an exam and treatment. You may want to put a cone on her if she is licking the area to prevent her from further irritating it.

He could have a skin infection, allergic dermatitis, fleas, and/or a problem with his anal glands. You could bathe him with a anti-bacterial medicated cat shampoo and see if that helps. Also, use a good flea prevention, like Revolution, Bravecto, or Frontline to prevent fleas. If the problem continues then he should be examined by a vet to determine the cause and treat. He might need an antibiotic, anti-histamine, and a corticosteroid to help treat. Your vet can also express his anal glands if they are full.

It is difficult to diagnose without seeing the bump but it could be an infection, cyst, mass, or an injury. The best thing would be to have your vet take a look at it to determine the exact cause and best way to treat. He may need an antibiotic, anti-inflammatory, or other medications to treat. Your vet can do a needle aspirate, if necessary, to help diagnose the cause of the bump.

Judging from the pictures you have provided, this could be a bacterial skin infection or ringworm. I would recommend having a veterinarian examine him so that the most appropriate diagnostic and treatment recommendations can be made. The sooner this is looked at the faster the resolution. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Poor Gary! These marks could be caused by him over grooming the area due to itching. This itching can be caused by fleas, mites, ringworm, or allergies. If he isn't up to date on his flea treatment, he will need a spot on treatment such as Advantage or Revolution. You will need to disinfect the environment as well. If he is up to date on his flea treatment, I recommend taking him into the vet for an exam tomorrow. The vet can do blood tests, skin scrapings, and use a Wood's lamp to diagnose allergies, mites, and ringworm. Once the cause of the itching is found, the vet can prescribe the appropriate treatment.
