Since introducing our 2 girls (aged around 7 months) to our 2 older boys, life has been calm and peaceful! Or so we thought... One of the girls, Emily, took a particular shine to 3 year old Button. The pair of them have spent hours washing each other, playing and generally having a good time. But the good time for Button seems to be completely out of control and suddenly, for the last 2 weeks now, he takes any opportunity to mount her, holding her tightly by the scruff of the neck and then after trying to mate with her, literally drags her around the room by the scruff. All the time she is wriggling and making little mewing noises. He is much bigger than her so she is completely helpless underneath him. And when I say all the time, it really is. Whenever he gets the opportunity to pin her down, he does, so she is starting to spend more and more time hiding under the bed away from him. But interestingly, when she does come out, she goes straight back to him and rubs around him purring!! So in a way, just encouraging him to do it again. Any idea why this is happening - I feel so sorry for her, he just bothers her constantly. All of them have had the "snip" so at least I don't have to worry about the pitter patter of tiny paws.
