From the chart we can see that the least active purebred cats are the Persian and Ragdoll while the most active breeds are Abyssinians and Bengals. The position of the Maine Coon surprises me to be honest. I have never seen this cat breed referred to as being inactive. That said you can see that the middleground of this chart is very similar in terms of activity levels. It is only when you get up to the domestic short hair and Cornish Rex that you start to see the more active cats. The Persian is by a long margin the least active even when compared to the Ragdoll.
