It may look like Rusty is just being kind and grooming Princess. But he has ulterior motives.
I’ve seen him pull this off before… and it keeps on working.
He will just “politely” keep on grooming her till she leaves the sunbeam. Then he will watch her depart and pretend to be heartbroken as he settles into the pre-warmed spot.
Poor Rusty – she doesn’t appreciate him…
