I wish I had the magic answer for you and your mom
When I lost my Cricket last spring, just posting here and reading all of the replies made me cry, but helped me begin to heal. I think all you can do is be there for her - call her lots - let her know you're thinking about her. If she's having kitty cremated (long shot and random), call and pay the bill before she goes to pick up. Paying that bill was *really* hard for me.
Hugs to you both.....
