Sometimes I have a question that doesn't warrant an entire thread. Maybe some of you do as well

My question is about how to better phrase a question lol
I think my cat is pregnant. When I got home this afternoon, I looked under the RV and saw a HUGE dead rabbit. She ate only it's head.
I gave the body to my dog to enjoy because the cat was done with it and I hate seeing critters killed and then "wasted"... but then I saw a perfect bunny ear. It's a little bloody at the end that connected to the head, but it's undamaged.
I then became curious if I could "cure" it and keep it without losing the fur on it.
The only word I know for preserving an animal is "cure" (maybe I have the wrong word?).
When I google it, though, all I find is info on making sick rabbits better.

What is the word I'm looking for?
