last ditch effort to save our family cat

Hi .My name is Brandie and backin Janurary of 2006 i adopted a cat from our local humane society as a family pet. He is 5 years old and i was very excited to bring him home to my hubby and 2 kids aged 4 years and 14 months. i hoped to teach my children to love animals with this cat but it has blown up in my face! this cat whom i will refer to as mr. furley wants nothing to do with my kids, in fact he hisses and growls at them and avoids them at all costs! I am going to try clicker training as i have tried everything else to no avail. i will report back to you after some time.
