What are some of the most popular funny animal comics from the 1970s?

Some of the most popular funny animal comics from the 1970s include 'Calvin and Hobbes' (though it started in 1985, its influence and humor resonated strongly in the 70s), 'The Katzenjammer Kids' (a long-running comic strip with roots in the 19th century, but continued with updated humor), 'Little Lulu', and various one-panel gag comics featuring animals like cats, dogs, and birds. These comics often played on anthropomorphism and silly situations.
