Go here. You can sign up to "click daily" for a bowl of food for a shelter dog or cat. They will send you a daily reminder. It's a good deal.
And don't forget to vote for your favorite shelter to win $300,000 (I thought it was $100K but must've missed something). I recommend Pets Alive Westchester, since they are great and in the running. They are located in Elmsford, NY and their name is Pets Alive Westchester.
You will need to enter location and shelter name. It takes less than 30 seconds a day.
Don't forget to vote each day!
