Compose and send a letter each to local schools - pick a specific teacher is best to address it to - and to local churches, listing specifically what donations the shelter needs. Old towels, old stuffed toys, any cat or dog food ... and, most importantly, who they can contact at the shelter to arrange a time to drop stuff off.

And have a list attached of the volunteer opportunities and parameters if people have to be a certain age or have any kind of trainng, or whether, for example, a Scout troop could volunteer to come by once a month and clean cages and walk dogs, for example. If various groups volunteered, they could be spread out throughout the month so that it happens regularly.

Stress that time is just as important as money, and if for example, you are poor and on a fixed income so cannot donate anything, but have time you could donate, that would be great!
