Is it me or is there something odd about my kids?

I have noticed some subtle changes in my kids behaviour. I suggested to Mrs R that we cut back on the chocolate as they get a bit hyper at night but she thinks that it is just a phase. We've had to hide the phone as the little buggers keep wanting to call home which is odd. We haven't seen the cats for a while either; every since Miss R said she thought the cat looked a bit "fat and juicy".
