I'm always donating any change I get back at the bowling alley to the SPCA tins they have there, and when we go to Petsmart, I always add the extra $1 to help homeless pets. I'll probably bring some stuff to the SPCA we adopted our kittens at, as well as donate monetarily to them and/or the Humane Society. I have a very soft spot for homeless animals! They weren't given a choice.
