My cat is still itching. Could it be mites even if tests are negative?

Updated on September 23, 2025

Pet's info: Cat | Siamese | Male | neutered | 6 lbs

My cat has been severely biting, scratching, etc. ever since we adopted him, from a shelter. The vet hasn't Found mites but has given antibiotics, eye drops, (several skin scrapings), and finally new food. He is Still really itching. Can a cat have scabes or mange without finding the mites?? If so, how can I convince the vet that it might be this?? My cat needs relief. Thanks, Kris

That sounds very uncomfortable for Coconut! I'm glad that he's already seen a vet to start managing this problem. Itching in cats can be due to a number of causes, as I'm sure you're aware. Certainly mange (Demodex or Sarcoptes mites), fleas, and allergies to food or environment are some of the biggest culprits.

It is still possible that Coconut has mites, but with several negative skin scrapes, I would be surprised if that is the case. You can start by applying a high quality flea preventative (Advantage or Revolution) once a month, if you haven't already. Some cats are allergic to the saliva in a flea bite and can become intensely itchy even after one bite. If your vet is concerned about food allergies and has started a novel protein or hypoallergenic diet, these can take 2-3 months to fully take effect. Be sure not to give other treats or table scraps and solely feed the new diet.

If Coconut is still itchy despite these measures, please schedule a recheck with your vet to discuss using corticosteroids. However, this would be contraindicated if mites are present.

Why is my cat still itching and red after allergy treatment?

I'm sorry to hear that Gofret is having so much trouble! There are a number of things that can cause itching similar to what you describe - it's true that allergies are one of the most common causes, but he could also have a bacterial or fungal skin infection, parasites like fleas, or even skin mites (mange). Your vet should test for these things if this hasn't been done already. If skin tests for all of these problems are negative, then it's likely that your cat has an environmental allergy of some kind since the hypoallergenic diet has not helped. In that case, you will probably need to use a long-term medication to control his symptoms such as prednisone, Atopica, or Apoquel. It may also be an option to have allergy testing done so that you can do hyposensitization injections if you wish - you can ask your vet for referral to a veterinary dermatologist, or get a second opinion from another veterinarian in the area if needed.

Dog scratching, licking, red bumps: anti-itch isn't helping. Why?

This itching can be caused by fleas, mites, ringworm, or allergies. Coconut oil will not help with these causes. If Patton 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 today or 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.

My cat is still scratching after 6 weeks on new food. Is it allergies?

I would recommend to wait up to 8 weeks before thinking about other causes. If not working, a skin scrape and more dermatological tests (including allergic testing on bloods) are required to determine if other causes are possible. 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.

My cat has weird itching spasms despite being flea-free. Help!

What a handsome boy! There's a few things you may try. To absolutely make sure fleas are not the cause (remember, if you have a pet who is sensitive, tit only takes 1 flea to cause a reaction), talk with your veterinarian about using an oral flea prevention called Comfortis. Try this for 2-3 months and see if it helps. Kahlua looks a little heavy, sometimes this can prevent them from being able to clean the lower back/around the tail. Weight loss will allow him to adequately clean that area and in the mean time, shampooing the area every 4-5 days or using a dry shampoo and a brush every 3-4 days will help to decrease the oil production and decrease itchiness. Continue using a fish oil though I prefer an omega 3 fatty acids supplement. Changing the food to Royal Canin may also help improve the skin quality. Allergies can also cause itchiness but I recommend to rule out the fleas first. I hope this helps.

Indoor cat scratching a lot, no fleas. What could be wrong?

This could be a sign of several things including environmental allergies, mites, ringworm, and food allergies. Without doing a physical examination on Shyannne it's difficult to say what it causing her to itch. Even if you are not seeing fleas, if she is not currently on a good quality flea preventative like Revolution you may want to start. You may want to try bathing with a soothing shampoo. Once a veterinarian checks her out they may prescribe a medicated shampoo. The Douxo line makes medicated shampoos and also mousses for animals that are more difficult to bathe. Omega-3s are naturally anti -inflammatory so these may help as well. If Shyanne's symptoms persist then she should be taken to your veterinarian. Her skin can be tested for mites and other types of infections. There are many treatments for allergies available as prescription medication. Thanks for using Petco Pet Education Center, formerly Petcoach and I hope Shyanne's skin issues resolve quickly!

My puppy won't stop itching; what's causing this persistent skin issue?

The only way to definitively diagnose mange (Demodex) is by skin scrapings which should be repeated every 2-3 weeks during treatment until 2 negative skin scrapings are found. Make sure that the flea and tick medication prescribed will also treat mites (milbemycin or moxidectin) and keep in mind that the dosage frequency is different for mite treatment than it is for flea preventative. Treatment needs to continue for 1-2 months after there is a negative skin scraping. Steroids are usually contraindicated in treatment of Demodex. Demodex mites are not contagious to other animals so your other dogs may not be affected.

My cat is itchy and bald after vet visit. Could it be cleaner?

Hi Barb! I'm sorry to hear that your cat is so itchy! I highly doubt that your cat developed his itching from a dirty exam table, but he may have had an allergy to the type of cleaner used on the table. Causes of acute itching are typically allergic in origin and can be due to fleas (less likely since your little guy is on Revolution), diet changes, or environmental allergens. When animals become extremely itchy, they can cause skin infections as a result of their scratching. At this point, it sounds as though your cat needs to go back to the vet to make sure he has not developed an infection and possibly may need a course of corticosteroids to help control his excessive itching.
