Not just cats have blogs, but cartoon characters too. Dilbert, the American Engineer has his own blog. Imaginatively named The Dilbert Blog it is, of course, very funny.
A caveat at the start of the blog is, "My blog is the only writing you’ll see from me that doesn’t first go through a professional editor. That means plenty of grammar and punctuation wrecks for you to enjoy. I blame the public education system". So you have been warned.
