My cat has a nose bump after new food. Is it ringworm or allergy?

This doesn't look like a classic ringworm lesion to me, but ringworm can have many different appearances. A bacterial infection or allergy would also be possible. I would recommend having a veterinarian examine Noody to determine what the lesion might be.

Thank you for submitting your question regarding Gijs. If the wound is just minor trauma, it should begin healing within 48 hours. If it continues to look smaller, then I would not worry about it. However, if it is not resolving or certainly if it spreads, she will need to see her veterinarian. Ringworm is a fungal infection that is common in kittens. It can start in the nose. It is diagnosed by plucking hairs and performing a fungal culture. I hope this information helps!

It is possible that Proust is having an allergic reaction or allergy causing the little pimples. The 3 types of allergies in young cats are food, environtment or flea. I recommend applying flea prevention every 30 days. You can try to use glass feeding dishes that you clean often and avoid cat food with fish or beef in it. If Proust will let you, you can try to give him a medicated bath too. However if this is not improving I recommend taking him to the vet for a good exam. It is possible the pimples are infection and need antibiotics to resolve

Thank you for submitting your question regarding Nala. I do recommend that she sees her veterinarian. The changes can be a component of her allergic skin disease. It could also be a new problem such as ringworm. Her veterinarian will ask more detailed questions regarding her diet, exposure to other cats and changes in her environment on the island. I hope this information helps!

I recommend to go to the veterinarian. Losing fur is not normal and may indicate something like ringworm (which humans can get), allergies, infection or skin mites. I'm not sure what the bump may signify but your vet will get a better idea from an exam. I hope this helps.

From the picture it looks like Neve may have a skin infection. This could be bacterial or something fungal such as ringworm. I suppose there could be a good connection if she has an allergy to the new food, but that may take a while to sort out. I would encourage you to have her evaluated by your veterinarian soon. In the meantime please practice good hygiene after handling her as ring worm is contagious to people as well. Best of luck and I hope she improves soon! Thank you for using Pet Coach.

I would recommend uploading a picture of Yui's nose for us to see. You can resubmit the question and upload up to 3 pictures. If it is not resolving then the next step would be a biopsy of the lesion. That would give us a definitive answer as to what is going on.
