How can cats growl and purr at the same time? And why does my cat attack my legs?

How can cats growl and purr at the same time? And why does my cat attack my legs? ~ Jessica

Dear Jessica,
It’s most excellent that you noticed that many cats can growl and purr simultaneously. We growl with our fierce throats and purr with our sinuous bodies. It is a fine, very fine feeling to enjoy our ancestral ferocity. Growling and Purring, Purring and Growling. It’s delicious just thinking about it. Similarly, attacking human legs, especially in a manner surprising to the humans, is part of our play and necessary to keep ourselves sharp and humans alert. Pay Attention!

Please profusely thank the next cat that growls, purrs or attacks you.

Best Wishes,
StarGazer, E.O.C.
