One of our cats has six toes instead of the normal five on each front foot. Since a six-toed cat contains more information than a five-toed cat, clearly, some mutations do indeed increase information.

That's not necessarily true. The number of digits appears to be a function of when and where certain chemical triggers are turned on and off; individual digits themselves aren't necessarily hard-coded into the DNA.

This is an excellent point. It is also why I keep puhing Neil Shubin's Your Inner Fish. Early on in the book he does a great job of explaining how regulatory elements control expression. It's how fins became legs, feet, arms and hands, and how bat wings evolved.
