Contact the Human Interest Editor for your newspaper and put a Press Release together outlining what you did for them, what they do for abused, abandoned animals. Explain how you are a big softie pet lover at heart and have 6 dogs, 4 cats, 30 chinchillas, (or whatever) and if you have adopted from there before that would prove you practice what you preach. Add some of their statistics as well so it helps raise awareness to their service and not just a "look at me, I walk on waterr". Get them to give you a glowing testimonial too!!!
Maybe you could include a offer a limited time only special of free protector for 2 rooms for a donations of cat/dog food, scat box litter, old sheets or blankets for kennels, treats or whatever. Then you could do another press release/blog thanking all the individuals by name that donated items during your "Raising Awareness" Campaign.
Maybe you can mention it in your blog and link the press release to it. Might get you more pet stain/odor removal work?
I don't know what I'm talking about any more..I'm just rambling, but maybe there are a couple ideas you can run with...?
Keep us broke dicks updated on what you put together because I've thought about doing something like this myself but I just haven't pulled the trigger.
