So my brother and I were discussing his cat Max ( http://catoftheday.com/archive/2011/October/17.html )

Max has been out of sorts for a few days and he is the first cat my brother ever had. Then we got to talking about cat ages and how that is calculated.

He found this website that supposedly calculates their age. I always knew a dog's age was 7 times a humans but never really knew any info about a cat's age.

Wondering if our seasoned cat owners here have any comment on this?
