Well, I only have one unspayed female, so my torture is not that of multiple females in heat, but torture of waiting for her to come into heat.......for the first time......so that I can get an idea as to when she would go into her second heat when we will be able to breed her. She is 10 months old and I keep checking for signs, but nothing. A little older is better I know, but I am so anxious. They say a watched pot never boils.....so maybe I should just quit watching.
But, if there's any truth to a female coming into heat by being around other females in heat, then by all means, send one of your girls over.
