My cat is always jumpy and scared. She runs around the house randomly, but not all the time. She usually does this after being outside. I know about the wellness center, and read the article about that disease. She only has a few symptoms, and not all the time. She has done this once before. It was last year. She refused to go outside for a bout four months. She is better, now, but still twitches and runs around crazy. She also flips her ears. What could be causing her to be so afraid? The other day I tried to calm her down and she bolted from me. She is eating fine and drinking fine. There are no other problems. I'm just curious if it is serious. She is five years old and had a blatter infections a couple of months ago, but I don't thin that has anything to do with it. She just twitches and runs around like something is chasing her. Any thoughts?
