Hmmm don't know about the wind affecting behaviour my 7 felines have been behaving strange now for about 3 weeks, being very hyper and mischievous, even my old girl of 17 years old has been playing frantically from waking at around 9am until around midnight with the odd cat nap to recharge their batteries.
Have given them Reiki to see if that helped but they have still been upto all sorts of stuff, from attacking wool whilst it is being used to getting into stuff they should not be getting into (cupboard door opens for 2 seconds and cat is in it) which is not the normal for any of them.
