Worried: My 8-month-old cat has a black nose mark. Is it ringworm?
Ringworm is actually caused by a fungal infection (a bit of a misnomer!), so Pickle's deworming treatment will have no impact on the lesion on her nose. That said, ringworm lesions are typically areas of hair loss and dry scaling, and rarely have thick black scabs. It is possible that Pickle injured herself, causing this black lesion. At this point, I recommend monitoring the lesion for another week. If it seems to be going away, there is no reason for concern. However, if the lesion grows, becomes more red or itchy, she should be evaluated by her vet. I hope that all goes well!
