Today I picked up my cat Zelda at the vet after her having spent two days there. The vet warned me to brace myself for how she looks: all her beautiful grey fur clipped; round, scabby bald spots everywhere; and, to top it all off, the cone of shame around her neck to keep her from chewing on herself. She's too sad looking to post a photo.
The good news is she's not terminal; the bad news is she has a severe case of ringworm. Daily medication and baths should restore her health although it will take a while for her fur to grow back.
