The Aura HD has an infra-red touch screen so the cat hair can be interfering with the light paths. About the only thing I can suggest is to make sure you clean all the hairs off the screen including under the edge of the bezel. I used to use a brush and blower that belonged to my camera care kit (similar to this one on Amazon but about 5 decades older)
