After the Dog Days of August, shouldn’t we have the Cat Days of September? Yes, this is an entirely made-up term, but it’s an excuse to post a few cat-related cartoons and see some of the various ways cats are portrayed in comics. Here’s a couple of Business Cats from LarK:
Garfield is possibly the most popular cartoon cat, so here’s one that may be a bit more timely than most, since ketchup’s been in the news lately.
This Get Fuzzy almost deserves a geezer tag, since soccer is now much more popular in the U.S. than it was a few decades ago and most of us can appreciate the action (or, at least, the theatrics of players barely touched pretending they are severely wounded).
A+? Who cares!
But at the other extreme we have the lively and intrusive cuties of Breaking Cat News:
No tour of various ways cats make their way into comics would be complete without one from B. Kliban.
That’s 8; we’ll leave our cartoon cats with one of their 9 lives left.
Comics I Don't Understand 
@ larK – The only spelling used in Germany is “Ketchup”,† but I was astonished to discover that your “catchup” spelling has been documented as the first established form in English.
P.S. † – My daughter has an annoying tendency to pronounce the final vowel as if it were an “O”, to my ear it sounds like “cat-chop”.
