Well, not exclusively... Animals are humans to me... My Pets come as a first priority when it comes to feeding and vets bills as they can't do that for themselves. I would hate to ever have to choose between an animal and a human.
So in answer to the thread title, YES, I donate to Animal charities, by buying an extra can of food when I'm in the petstore, or making a donation when I rehome an animal. I will NEVER EVER "buy" an animal (i.e a pedigree)... thats a different view though that I'm going to keep to myself in this instance.
I also donate to Oxfam by using their shops and Cancer charities as they have helped a few members of my family. As i can't afford to really donate money, I'll seek out other ways of doing it.
The british heart foundation gets all of my old clothes to sell (as well as GOSH) - SCOPE got 4 bags worth when I moved from Manchester. and I have been donating and buying furniture from Age Concern for about 6 years now. It's my first port of call for furniture in MK.
Have I redeemed myself?
(seriously though, I'm a lovely person, i'm surprised you took my hastily posted reply as seriously as that!)
