Why does my cat keep getting red itchy spots after vet treatment?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 2 years and 5 months old | 6 lbs

My cats are still coming up with these red balls that scratch. I was with him at the vet, he did all sorts of injections, baths and skin and fur treatments, but the stains are all over again. I am very worried. What could it be?

Thanks for using Petco Pet Education Center, formerly Petcoach! There is just no way to diagnose this just based on a description. This may be due to allergies for example. This could also be some sort of infection perhaps. This requires further diagnostics which would be done based on an exam. Your veterinarian would be better able to proceed with the needed diagnostics to try to determine what may be wrong. I would highly recommend you have him reevaluated by his veterinarian since things have worsened again. They may be able to proceed with further diagnostics and treatments accordingly. Good luck!

    Thanks for using Petco Pet Education Center, formerly Petcoach! It is hard to tell from the picture but it looks like he has a skin infection. I recommend taking him to a vet for a exam. He likely needs antibiotics and something to relieve the itch. Good luck and kisses to Patrick!

    Thanks for using Petco Pet Education Center, formerly Petcoach! I am afraid that it is not possible to diagnose this just based on a picture. This usually will require an examination and basic diagnostics. I am suspicious that he has been biting at his tail and this is possibly due to allergies. I recommend that you have him evaluated by a veterinarian for further assessment and treatment. They would be able to diagnose his condition so that he can be started on therapy. Good luck!

My cat was diagnosed as probably having some type of allergy bc he was licking himself raw. He got a steroid shot and it went away for about a month. He got another shot two weeks ago bc he started licking again and this time it did not work-?hes giv
Thanks for using Boop by Petco! I agree that this is possibly due to allergies. It really comes down to figuring out what is causing his allergies so that they can be treated or the specific allergen avoided. There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). If not improved in 1-3 months then it is time to move on and check for food allergies by switching to a novel diet (new protein and new carbohydrate). If that does not seem to be the issue then you are left out having to check for environmental allergies which require blood and/or skin

Is this a hot spot, an allergic reaction, or rash?
Hello and thank you for reaching out to Boop by Petco. Based on its appearance, that resembles a hot spot, or a moist-dermatitis brought about by licking. If it is at the base of the tail, this is a common place for cats to have a flea allergy/infection. I recommend having Baloo seen by a veterinarian who can perform a skin scrape test/cytology to see if there is evidence of secondary bacterial infection and/or other types of external parasites, such as fleas or mites. Baloo will need to wear an Elizabethan collar so that he does not continue to lick at this area and cause further trauma. He will also need to be on monthly topical flea and tick preventatives, purchased from your veterinarian. Flea and tick products that are available in food and pet stores are NOT effective OR safe for use on cats or dogs. I hope this is helpful!

My cat has has itch skin on belly with little dots. Is there a topical I can use until she can be seen by a vet
Thanks for using Boop by Petco! This is possibly due to allergies. A secondary infection is likely and also needs to be addressed. A topical is not likely to be of much help here. You could consider using an e-collar to prevent licking if that is currently an issue.

My cat Oliver is a Siamese/Tabby mix and he has been compulsively licking/scratching himself for the past 2 weeks. He now has a nasty wound on his shoulder from scratching so much. I have hot spot spray which seems to help but the fact that he’s wet

Used spot on, on the cat a few fays back and i think she's had a bad reaction, it's went scabby and a tad yellow, should i take her to the vets? Or is there a cheaper option that i can maybe buy?
Thanks for using Boop by Petco! This looks like a focal infection. You can try to use a topical medication containing chlorhexidine twice weekly for 2 weeks. If there is no improvement or in the meantime this appears to be getting worse, have her evaluated by a veterinarian for further assessment and treatment. Good luck and have a good one!

I would like to know what I can use to heal my cats sores please bought conditioning tablets and I clean her wounds with dettol and use frairs balsem and staal druppels to heal but she is still scratching help please
Thanks for using Boop by Petco! This is likely due to ear mites or possibly allergies. I recommend that you have Coco evaluated by your veterinarian to check for these possibilities and treat accordingly. This looks quite severe and needs therapy as soon as possible. You can use an e-collar in the meantime to prevent further self-trauma from the itchiness.

My cats been itching undee his neck and hes got little red bumps and scabes and there not bleeding or anything he lets me look at them and touch them so it doesnt hurt him i just wanna know whats wrong and how i can treat it we have no money to take
Thanks for using Boop by Petco! Skin lesions like you are describing can have a variety of causes, including skin parasites (fleas or mites), an infection (bacterial or fungal), allergies, or another underlying medical issue. I would recommend he be evaluated by his regular veterinarian to determine the underlying cause for his skin lesions, so he could start any treatment (antibiotics, anti-itch medications, parasiticide) that he may need. In the meantime, I would clean the area will diluted betadine if possible and then keep it dry, and trim his nails back as much as possible to keep him from scratching at it. Good luck!

My cat has a spot about 2/3 of a dollar. No scabs, and blue size quarter line in the area. Do you know what it could be?
