I am so sorry for your lost. All my condolences.
I don't think anything will make you mom feel better...
But maybe you can bring a nice picture of Heidi to an artiste that do pet portrait and give it to your mom. Just a thought.
And when ever she is ready.. get her a yorkie puppy. He won't replaced Heidi but it will fill up a little bit of the emptiness...
