My Lucy is tormenting Marshall almost the same way.I don't want to get too mad at her because I don't want to get her angry and make it worse.Sometimes I think it's more like playing but I know Marshall is somewhat getting afraid of Lucy now.And Lucy knows this.Maybe that's why she does it.. I don't know.I just keep picking either one up and make sure I pat Both of them so noone gets jealous.I'll try that for awhile.Good luck with Pouncer.You can't get to mad because it might make him want to lash out more.Hopefully it will pass .
