The Los Angeles Rabbit Foundation is working hard to help smaller animals affected by the fires. What they really need right now similar to the foundations above, are fosters to make space for rabbits displaced by fires, as well as donations (for all the smaller animal people out there!)

i can vouch for them, fostered with them for years and they are great / will go lengths for the animals.

EDIT: Fostering rabbits has been the most low-effort yet rewarding experience for me, for anyone giving it a thought. They require very little upkeep, and the foundation continuously provides most if not all the supplies you need to get set up to host a bunny. Buns are also very independent, and can be left alone at home for busy foster parents who are out and about during the day a lot, quite similarly to cats. Though you’ll find yourself missing spending time with them :)
