After finding out that the mother cat had FIV, the vet recommended that I raise her kitten by hand. I was successful, however the kitten seems to have behavioral problems. She was the only cat in the litter and was raised solo. Although healthy she tends to look bored most of the time. Although she expresses an interest in going outside she has refrained from doing so after being attacked by an older cat outside. She is only comfortable being around her younger brother, but seems distrusting of other cats. How can I help her with her boredom and socialization problems?
