Kittens climbing screens...help!!

Hello,

I am just wondering if anyone can give me advice on how to stop my two
kittens Zazu and Zu=F1i from climbing the screens in our apartment. They
are generally well behaved kittens, but the screen climbing is going
too far! They have a scratching post, which they use all the time, and
also a spray bottle for when they misbehave. The water bottle doesn't
seem to do the trick when they are on the screen. I read a previous
post on this group about putting spare change in an empty pop can, and
I plan on trying it as soon as we have an empty can. If anyone has any
suggestions, please let me know! Thank you!
