Hi everyone, I am new this AMAZING site, I have a 2 year old neutered male, and a 10 month old female. Hank (Williams ) & Dolly (Parton). I noticed yesterday that she is not as playful and outgoing as normal. I think she may possibly be going into her first heat, I have had two other females in the past but do not remember them being like this before they went into heat. She is normally very energetic, is 10 months normal age for first heat? Thank you!
