Hi there. I'm sorry to tell you this but Huskies are notorious for killing cats. It is unfortunately in their nature to chase and kill things that run from them....... This is going to be VERY difficult. If Villian did not run from him there may be a chance of getting some resolution but if Villain is scared (which is understandable) and he runs, the higher the chance your dog will eventually catch and kill him. I'm not trying to freak you out but I want you to be realistic. They are not a breed known to be good with cats or even small dogs. Of course there are some that are fine but if you have to play the odds.......most are not.
That being said I feel like your only real shot is to have a dog trainer come to your house, assess the situation with all the family members and pets and then hopefully they can help you try to modify your dog's behavior and response to the cat. I will tell you, instinct is a hard thing to overcome.
I recommend you try BarkBusters. They are really good. I don't think there is a trainer right in your city but call/email them anyway and see if they can help you or recommend someone in your area that can.
