Kittens are unpredictable. Misty when she was little she was scared of everything new. She is 5 now and once in awhile she still has frightened look on her. I remember a couple years ago my husband cut a tree down outside in the backyard. Us not knowing Misty watched the whole thing we came in the house and she was just trembling. We could not figure out why. Later my husband picked her up and went to the patio door to look at the tree he cut and she went pazerk and jumped out of his arms and ran away.She saw the tree go also heard it and scared her. For about 2 months she did not go near the patio door. For awhile we called her our scarty cat. She is totally an inside cat. She hates it outside.
