Is anyone else familiar with this phenomenon? I imagine it is more obvious in multiple cat households but it can certainly be experienced with just one cat. I love it when cats swirl and when my cats do it all at the same time there is no better feeling. Swirling is decidedly pronounced first thing in the morning or when one arrives home after some absence. It is the whirl of cats around your legs. Trusting, upturned faces and tails aloft they seem to be one continuous curving, twisting line, of purring cat form. It is the best welcome home after a crappy day, and the most cheerful start to any morning. Swirling is acceptance, support, love, validation and optimism all rolled into one delightful gesture.
