Sometimes buns will lick your clothes - or otherobjects with your scent - instead of you. Licking is definitely a signof affection - it's one of the things they do when grooming each other.If your bun likes to pull on your clothes, they're grooming you. Theyhave a lot of ways of expressing affection, things that aren't soobvious to most of us (me, too). Chinning is another thing that manybuns will do to literally mark you as theirs.
My bun, Nibbles, licks my hands a lot, but it took quite a while forher to get comfortable enough with me to do this. It's a hugegift, and I don't take it lightly.
