If cats had wings would they chase birds in the sky? Would pigeons be safe? Would they swoop down like owls and catch voles from on high?
Horses have Pegasus, cats could be mythological, why not. They were worshipped as gods in Egypt, imagine them flying up to tree tops. Mioawing a Dawn chorus.
With genetic modification they could grow huge wings to allow them to hover like drones, waiting to see when their owners come home, spiralling down to perch on feeding stations.
Their coats could be patterned with spirals and chequer boards in blues and purples.
