My cat (1 year old) has been getting lesions on his lips ever since I can remember. They seem to heal eventually but then come straight back. About a month ago we got a biopsy done and it came back as "Cladosporium" - a very uncommonly seen fungal infection in cats. The vet was initially was going to refer us to a specialist vet for treatment however decided that we should trial a 3 month course of fluconazole 50mg twice daily first. He has been taking the fluconazole for 3 weeks now with some slight improvement. However what I have noticed in the past 2 weeks is that his eyes have become quite watery and he is
constantly squinting all the time. He doesn't try to itch his eyes (or the lesions on his mouth) and is acting normal behavioural-wise. Is this likely to be related to his infection? Would you suggest continuing with fluconazole for another 2 months or going straight to the specialist? From what I've read first line treatment is extensive surgical removal of the lesions and if that can't be done itraconazole is the treatment of choice. I've attached a photo of what his mouth is looking like at the moment.
Thank you for your advice.
