You could also put an E-collar on her, which unfortunately, she won't like. Cats usually heal quickly, though, so you may only need to use it a couple of days which will give it a chance to heal and let you clean and apply medicine to it.
I recently saw an alternative to the E-collar in a Care-A-Lot Pet Supply catalog. It allows cats to move much more freely and they're able to eat and drink comfortably. It's called a "Bite Not" collar. The website is www.carealotpets.com
BTW, what a great picture of Easter - she's a cutie!
