The humor presented here is of the weight of a sub-atomic particle. When it is not my intention to fight with my fellow reviewers over whether kittens are a humorous subject to mention in a given scenario, the use of felines as a punchline is really getting too tired both in this wiki and amongst the broader populace of the Internet. Besides, cats aren't really all that funny when they are used in such an awkward, poorly-timed fashion as one that is demonstrated in this article. Namedropping is no substitute for true comedy - think about that.
The concept featured in this article is at best an attempt to gamble on the reader's perception of keywords and devices such as "kitten" and "grue" at the potential expense of the entire article's value. Hence, appropiately, the article is now in the state of comedical bankrupcy. Although I would really like to suggest a way or two to improve this article, the best way to deal with this is to simply start over with a more solid concept such as one that is truly relevant to the subject matter - whatever that means to you.
Prose and Formatting:
I can't say the formatting is really that hopelessly bad aside from a few minor issues with first level sub-headings. Normally, we don't use that particular markup in wikis such as this because it coincides with the font and size of the main title itself. If you happen to find yourself in trouble with wiki markups, there are plenty of guidelines and tutorials available both here and in Wikipedia. Try get a hang of the markup techniques first, and then worry about the formatting later.
Pictures are better present than absent. I am impressed with the fact that you did go into the trouble of finding suitable images for this particular subject, although there is certainly room for improvement in regards to the placement of such images and the use of captions.
A messy article with no genuine direction and, ultimately, a wild attempt at humor with no apparant success.
