Background for Floral Cat

I have this orange floral cat that I want to put a circle around and fill the background with the pattern of the inverted tourquoise cat pattern.  I want the flowers to be the same size as the orange cat and for it to be done seamlessly.  How do I do this?  I had made the circle 5000px for the orange cat.  And just ignore the other 3 solid cats.  Thanking you, in advance, for help.
