My kitten is fearful of things?
I've recently adopted a three-month-old male kitten who had been living in abysmal conditions for the past months. He was caged the whole time, dirty, and his fur was matted.
I had him groomed and checked by my previous cat's vet who has him on meds for his existing injuries. On top of this, he doesn't seem to know how to use a litter box. He's terrified of it. What should I do to make him less fearful of things?
