The Mom had gone to sit down for a few minutes to rest her back and came back to see why the dog flap was making a noise - and guess who she caught in the act - and what "IT" did to MY brand new doggie door !! To say Mom was not happy is an understatement. Add this to Mom's new glasses that "IT" chewed up last week and "IT" is quickly wearing out "IT's" welcome. It would take pages to list all the things this tiny little destruction machine on legs has ruined. My Mom made "IT's" Mom pay for the glasses and she will be making her pay for a new flap too and at $38.00 it's not going to make her happy either !
