in my experience I would say stay away from Huskies for the cat´s sake.... but as you can also see Glacier has Huskies and cats living together... although and she can confirm that, they have to be supervised.... and also as they may follow indoor rules...indoor cats being out are fair game...sad but true...

Huskies to have prey drive which can be subdued or very high.. but it can be triggered anytime... so I agree with Giselle... an older dog know to tolerate or even like company of cats is your mom´s best bet....

a pup might be what she wants and can be "trained" to live with cats peacefully.. but it will take time and effort and sometimes frustration... so she might consider that too...
