That's a beautiful quilt! Sometimes when we see something too much, we get used to it and crave something different. At least that's something that happens to me.
I only do end to end quilting, so if you want quilting fully customized to the quilt, I can't help. Otherwise, I would look for an end to end cat pattern and go with that.
Whatever you do will turn out to be the perfect quilting for it. Please let us see it when you're done.
