Why does my kitten have scabs and a lump after using a flea collar?

Probably just flea dirt and it sounds like she actually has a flea allergy. Flea collars do not work with the exception of the Seresto Collar. One Seresto Collar works for 8 months so it is comparatively inexpensive compared to other products. I suggest you get her some better flea control. You also need to treat every pet in the household to keep them from bringing fleas in the house and you need to treat the house/yard too. I suggest these products.

Best wishes.

Yes it would be ideal to remove the collar and use another type of flea treatment, waiting at least a couple of weeks (you can use comfortis tablets). It is very likely that both the scab and the hair loss is due to the collar which is causing skin reaction/allergy.

Thanks for using Petco Pet Education Center, formerly Petcoach! 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!

Cats can be very sensitive to flea collars, and I would recommend taking this one off now and allowing the skin to heal. Unfortunately, herbal remedies are not reliable in preventing fleas, so I would recommend a topical flea preventative like Frontline or Revolution. Once the skin heals, you can try a Seresto collar that lasts 8 months as it seems to have less reaction on the skin.

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Xenna. I would advise having your veterinarian evaluate her especially if the integrity of the skin is compromised. This can lead to infection and more itching and scratching which will cause more damage. Your vet can evaluate the area and advise an adequate treatment to get her through this. I would contact the manufacturer of the collar and report this adverse reaction. Hopefully, along with your veterinarian helping you, they will offer to cover any medical costs associated with you using their product. Good luck

Yes, you can use A&D ointment but I would not be optimistic that it will do much. Her skin looks pretty painful and I think it would be best for you to get her some treatment from your vet. She probably needs some antibiotics and anti-inflammatory medications. There are MANY, MANY great flea treatments out there now. Flea sprays do not work well nor do they last very long. I don't think you should use that in the future. It is best to get a flea prevention from your vet. I am very worried about you saying that he seems to have "balls" associated with the back teats. That could be cancerous tumors. My recommendation is that you take Bubba for an exam. He really needs to be examined in person by a vet.

Fleas are never a fun surprise! Indoor cats can acquire fleas if they come inside on your clothing, through open windows, or on other pets in the household. Even though you have removed all of the adult fleas on Daisy, those adults have likely already laid eggs that will be impossible to remove. Flea collars (with the exception of the Seresto collar) tend to be very ineffective. It is possible that the collar may be affecting her negatively. Since Daisy has been relatively lethargic since you put the collar on, consider taking the collar off and using a high quality flea preventative medication, such as Advantage, Bravecto, or Revolution. Be sure to use one of these preventatives regularly for at least the next few months to break the fleas' life cycle, but preferably year-round. Cats can acquire tapeworms by eating fleas infected with tapeworms, so it may be worth taking a stool sample to Daisy's vet. If Daisy remains lethargic, stops eating and drinking, or develops any vomiting or diarrhea, she will certainly need to go to her vet for further evaluation. I hope that all goes well!
