Stray rescue cat scared of anything black

I have taken in a stray cat about 1 year old maybe a little younger. We dont know his history he would go to house to house for people to feed him is what we were told. He tryed running into a store thats how we found him. He had a bad upper respitory with sneezing blood the vet gave him med. We have had him for a little over a month he use to be very coudly know he will lay by your feet loves to play but will attack you and if you move to the next room he will sniff you out and try to get you and will bite and bite wont let go. Now He is scared of anything black and will hit it and jump back. like shirts, a shoe, remote, pillow and peoples hair and it seems any thing black he walks by it and he jumps. In the beinging i had a pillow on the chair i put it by him he would freak out and claw the air. I'm not sure why i dont know his history he was a stray we took in so i'm unsure.

please help, Houdini the cat

thanks CD

well Houdini no doubt led a very stressful life from very young, he was perhaps attacked and frightened by something black, thats just a guess b/c theres really no way of telling is there...kitty will need lots of love and attention is a calm home to allow him to overcome all his fears and anxieties..good luck, keep us updated on how he is doing..

Whatever your can is reacting to, it isn't because it is black.  Cat are colorblind for the most part.  A cat's sense of smell, sound, and motion are much more likely to cause a reaction than the color of anything it sees.
