“Last week i was petting him and noticed like hard fur sort of stuck together like it was wet or something? I kinda pulled it really softly and the whole chunk of fur just easily came out in one piece. The skin is completely smooth and normal underneath but i’m panicking so bad it’s ringworm.”source ↗

“my cat overgrooms massively i also realized. i thought he was allergic to fleas or having some weird hormonal thing because of how the hair was fading away but he had an abscess that led me having to cone him for several weeks and in that time the hair grew back which made me realize he really just eats at himself.”source ↗
