My cat has eczema-like rash on leg, keeps licking. What to do?
Hi and thanks for using PetCoach! Sorry to hear about Darby. Definitely looks like an angry lesion that itches a lot. Not 100% sure what this is but it looks like part of the Eosinophilic Granuloma Complex. Here is a link- http://www.vet.cornell.edu/fhc/Health_Information/eosinophilic.cfm
Otherwise this could be a bacterial skin infection, a skin mite infection, external parasite problem (fleas, ticks, etc), allergic reaction, among other things. You should take Darby to your vet and let them examine her. Your vet will gather a detailed history and evaluate Darby. They will then propose a diagnostic/treatment plan based on their clinical findings. Possible tests include skin scrape, skin cytology, etc. Treatment could include antibiotics, anti-itch medicines, an Elizabethan collar to prevent licking, etc. The licking has to be stopped or this will never heal. Cats tongues, as you probably know are very rough and will continually irritate the area when she licks it. Good luck
