The orange tabby is the male and the brown calico is the female.

As Mira is finishing exploring the female, it reaches out with it's 
forelegs and grasps the Doctor's arm. The claws in those three fingers 
are sharp and penetrate the sleeve of her longsleeved shirt and cause a 
sharp pain in her arm. It doesn't appear the animal is attacking, so 
much as it appears to be playing in its sleep. It makes a chuckling 
grunt while continuing to purr.
