You can use uncooked spaghetti for the whiskers. Sometimes I dip the spaghetti in melted chocolate or I pipe over them if they're not too long.
To do that, fill your bag with icing and fit it with a round tip large enough to go around the spaghetti stick. Stick the stick into the tip, squeeze the bag and pull the stick out at the same time. You'll have the stick coated with icing, and the part you were holding onto is the part that you can stick into the rabbit's cheeks.
Or, Thai rice noodles. They're whiter than regular spaghetti. Check out the pasta and Asian sections of the grocery store. It's fun to shop for whiskers.
Use the spaghttis sticks adn paint them black with food coloring. let dry before inserting.
Thank you for your ideas! You would not believe it, but I had no spagetti at home , so I've put florist wire for whiskers...
