Part of the reasons that 'The Simpsons' has been as popular as it is, and has survived for as many years as it has, is that it's been able to make caricatures of many people we've encountered in our lives. Almost all of us have come across an older woman who's a little too keen on cats.
The woman in this picture is taking things to the extreme, though. Cats are capable of walking themselves. They don't need to be taken to the shops with you!
