I love the MUTTS comic strip and it's creator, Patrick McDonnell. He mixes in fun and humor with important messages about animal welfare and issues.
According to the site:
McDonnell's website, muttscomics.com, promotes his animal and earth friendly philosophy. Consistent with McDonnell's concern for the environment, all of the MUTTS books are printed on recycled paper. He and his wife Karen O'Connell are vegetarian and happily reside with their formerly feral cat MeeMow.
Thank you, Patrick for the work you do. Your strip always makes me think... and smile.
