You can decorate such works in conventional photo frames. The kittens themselves are bright enough to be spent on a special decoration. And black cats, and striped, and pot-bellied rainbow look equally great.
Cross-embroidery of a cat( video)
You can devote a lot of time to embroidering a cross with cats - a simple village kitten, or a mysterious Cheshire cat, or maybe you will be able to portray your Permian or Siberian pet - in a special program developing a scheme for photos.
In any case - a pleasant process and an excellent result!
