I would do paw print blocks as an additional border.
Here is a link to a blog that gives directions for a simple pieced one. There is an annoying banner along the bottom of the page to subscribe but you can view the pattern without subscribing:

And here is one to a more elaborate paper pieced block from paper panache.

If done in subtle colors it won't detract.
Another option is to put a solid color border and quilt paw prints like I did in this quilt: https://www.quiltingboard.com/pictures-f5/puss-center-exercise-fmq-t54829.html
