Urine trouble, hope you're feline guilty

I just clicked over to Stuff On My Cat to check out the latest photos (the vacuum cleaner one is a classic), and happened to notice the Google ads on the right hand side. The third ad has me completely baffled:

This is wrong on so many levels. What does cat urine have to do with designer handbags? Why do the advertisers think that a designer handbag is the most appropriate thing to give to a cat owner? Is the bag lined with kitty litter? And Why Is Every Word Capitalized?

What the heck is going on here?
