Small dogs and big dogs are dogs. Just because they're a different size, does not mean a small dog will any different around a cat that a big dog. Papillons and JRTs are both VERY active dogs, as are Huskies. I don't know a whole lot about Huskies but I do know that they have a VERY high prey drive, higher than a lot of other dogs. Are there certain personality/temperament traits you/your brother would like in a dog? are are you/him just basing is on appearance? If you get a dog from a reputable breeder, they're all going to be expensive. It's not just Huskies. I've never had a cat & probably never will so I'm not sure if you'd need to get a kitten with a puppy, some people do this but others don't. I also reccomend that until you can fully trust a dog to be a lone by itself when you're away, to put him/her in a crate. Not everyone does this, but I feel it's important. Sorry I'm not of much help, but I hope I was of some help....
