There are plenty of things cats can enjoy to celebrate a birthday, even if they have no concept of why one day should be more special than another. However, a day with balloons, ribbons, games, something good to eat, and a nap is a really good day. And Simon's Cat is definitely a party animal!
Simon Tofield made a short but colorful video in anticipation of Simon's Cat (the cartoon) approaching ten years of age. That's still a few months away, but who cares? We'll celebrate anytime!
