If there are any animal shelters in your area, you could ask them if they know of places that rent to animal owners. They might also know of a temporary foster home that would be willing to help out for a short time until your mom can get relocated.

Privately run animal organizations will be more help than government run ones. They know someone who knows someone who might ............. Government agencies don't need the contacts for foster homes. They don't care if your landlord will or won't accept an adopted animal, so they don't keep lists of animal friendly places.

You could even discuss it at pet stores in your area. The more people who know you need help, the better your chances of finding a solution.
