It varies from character to character. Linda has a mid-length fur but it’s very fine and holds to her form like feline fur- Mia and Ri are similar but with shorter fluff. Jane has coarse but short fur while Emily and Seraph are fluffier. None of them save Mia or Ri would do well with tights or stockings- which is why many of them prefer light, loose or simply no clothes. Thankfully, the Fur Feather and Scale act doesn’t require them to wear anything that causes discomfort.
