She died 2 years later. Assuming she was old and/or in poor health, I can absolutely understand not wanting to move. It’s especially stressful for the elderly who may have lived there for decades. And it’s not like she could take the money into the afterlife anyway.
For the first half year, I had to escort my now-wife down my hallway with a broom or towel to fend of my cat who did not like sharing me.
And she had several cats of her own. When I warned her up front about my crazy cat, she was so cocky.
