Yep. The cat is getting seriously seriously upset every time DD cries. They both are but the male has started mounting the female and biting her every time DD lets out a screech or cry. Because the wee one is starting to toddle about and is finding her voice this happens a lot 
They're house cats so it's not like they can even bugger off outside when she's having a fit. I'm not sure how to soothe the cats when this happens or if it's something they'll get over? I'm obviously getting increasingly upset at the thought of them getting stressed out. We've tried the Feliway thing but it didn't make a difference. :(
