I just adopted Peach from the shelter and unfortunately its one where I'm responsible to spay instead of them before she comes home. She has an appointment on 11/18 to be spayed but I think she is in heat now by the way she rolls around and is very vocal (of course we just met so maybe this is normal for her?) My male is fixed and we are keeping her inside anyway, I'm just curious how long a heat lasts? Any other advise? I havent had one go into heat before.
