My burmese girl started calling at 2 weeks shy of 5 months at the end of October - was a shock, I thought she wouldn't as it was so cold and was in denial for a couple of days. My other girl is a Vervain so was spayed at 13 weeks with no problems - KozyKatz spays her girls before they go all the time and tbh it was nice not to worry about it myself.
