Just in case you’re serious, taxidermy is not a good option if you want a faithful representation of how you look like. Taxidermy often results in not exactly the same look something had when they where living because replicating exactly the bones and cartilage to put the skin over is not easy.

This is OK for some random wild animal you don’t care about representing the individual it once was, but for pets it usually results in unsatisfactory results, and for people it’s just very uncanny because our brains are very good with human faces.
