Pets' Fate After Involuntary Psychiatric Commitment

Today I'm not posting about my cat. Do I ever wish I were. I'd like
to know if anyone on this group can tell me what would/will happen
under the following circumstances: An alcoholic family member who is a
pet-collector (no cats; two dogs; more than fifteen birds) is
indigent, refusing contact with family, and possibly may have to be
committed for psychiatric observation against her will.

If she wants "revenge" against family members for the commitment and
tells the authorities who take her into custody that we are not
allowed into her house (the only people 1) willing, 2) *very*
interested, and 3) financially able to care for all these animals for
an indefinite period), what will happen to them? Will the local
humane society immediately seize them?

I'm heartsick beyond belief this morning and don't know how much more
I can stand of this unbearable situation. FWIW, we are assuming the
animals aren't being abused/neglected, but since the relative at this
point will not allow us into her home, we can't tell for sure if
either she or the animals are eating.
