rash came up recently. no clue what it is, but her fur is kind of crusty and yellow nearby so i think it’s secreting some sort of pus. or it could be pee that somehow got up there, i dunno. what could cause this? we plan to take her to the vet but money is tight. if it’s super serious of course we’ll go immediately but if it’s something we can solve at home i want to know before going and getting a vet bill
