I think Peggy may be going into heat. She is 6.5 mos old (DOB: 10/23/2010).
My neutered male has been trying to hump her for days, and today Corin (4.5 mos old) started trying to hump her. Katie, our spayed female, has also been trying to lick her vulva.
Is it possible for her to be going into heat in the spring as a first heat?
