Internet for Cats will give your precocious felines everything they need to prowl the information highway. They'll learn how to trample keyboards, use cat ESP on gopher servers, take control of a mouse, and send other cats spicy e-mail. Plus you'll learn how YOU can find your way to all the coolest cat stuff on the Internet.
I got this book in the mid-90s when it came out, when I was just a kid and the Internet was a brand new thing for most home users. This book introduces an Internet that no longer functionally exists in the world 25 years later. It's a fascinating look back at how things were, how simple the net was back in the day, and all done through the lens of catty humor.
I always wish it went a little more in-depth in the universe it presented of online cats, but I still enjoyed the reread today.
