I have had my cat "Cricket" since I brought her home from the A.S.P.C.A.four years ago.She is a house cat and has never been outdoors.My Wife and I are the only 2 persons in the household.Does anyone have an answer as to why she is easily startled,and overly cautious,even concerning items she has been familiar with for years.She has never been mistreated,or around anyone prior to us who could have done so.She approaches EVERYTHING in a cautious manner,even a box that she sleeps in constantly.This isnt a normal behaviour is it???
