Just over a week ago something happened to my 4 year old cat. I am not sure what happened but he leapt into the air scared. This is a jumpy cat who does this a lot so I didnt think anything of it. However, this time he will not go back to normal. It has been over a week now and he is still acting like he is constanting on the look out for something. He is peaking around every corner and gets really jumpy at anything. He won't play either because he is scared of the toy. He is still eating and everything normally and when he is in one of his few safe places he loves to cuddle and acts just like normal. This is the weirdest thing. Any idea what could be going on?
