When I first found my cat Dusty he had been chased by dogs and was very scared and timid. He kept tucking his tail between his legs and slinking low to the ground. After I brought him home and he got used to the place he was fine, no more scared behavior. Last night I had some friends over, and although Dusty gets nervous when other people are around, he is getting used to them since they are over often. I noticed that he wasn't around and I simply assumed he was nervous around the people again. However, this morning he is still hiding, and he won't go to his food or water bowl (or the litter box). When I found him, he had his tail curled up under him again and keeps staring wildly around like something is there frightening him. Since I am the only one home and there are no loud noises, I am puzzled! He's not scared of his brother because King will come near and Dusty does not cringe. Same with me, but as soon as he is no longer underneath some little hidey hole he becomes terrified! I am getting a little bit worried. Does anyone know what could have caused this and what I should do? The things I did when he was a kitten to calm him down aren't really working!
