can a small donation to a charity really do much ?

Maybe it won't help them much, but it will teach you to be more generous.

DO YOU WANT TO FEED AN ANIMAL?

+$20 is $20 more than they had before the donation...

That could probably feed a lot of animals - since in that situation all they need is to be fed - it doesn't have to be gourmet - but even basic pet food costs money.

$20 a month is very generous IMO!

I've never donated at that frequency, but I can't really afford it... just a little bit here and there... but again 0 verses some amount I'd say that 0 is worse than at least a little something and I totally tip my hat to $20 a month. 

It is very thoughtful and kind. 

I stopped donating because I would tell the charity that it was going to be my last donation and within a week they had send another letter asking for another donation.

You might think that $20 doesn't mean much. Instead, how about you showing up at the shelter with a couple bags of Kitty Litter?  I have done that before and most shelters are Thrilled when that happens. 

As the old proverb says, “Every little helps”

The Scottish saying is equally apt “Mony a mickle maks a muckle”.   A lot of small things combined make a big difference 

The smaller the charity the better.

The big charities are Employment Centers.  Being that only 10% Must go to the charity, the Rest is wages paid to the people who beg for the money. 

That 10% also goes to the Director  Secretary, and Treasurer wages, as the rest of the charity is usually Volunteers.

Do your research on the organization.

Yes!
