Help me help my cat, Moscow

She is a few years old now; very sweet, and timid. I found her during a thunderstorm a couple years back behind a grocery store. She hasn't left my side since.

My family and I agreed to foster a stray dog a few days ago, named Chester, and until tonight, he has been a dream come true. We discovered he was weird about cats and decided to speed up the home-finding process for him, as we have two.

We kept them separated but tonight we had a horrific incident occur. Chester barged into our bedroom and attacked Moscow. My boyfriend, Douglas, was able to get him off her (and was injured also in the process) and rushed her to the animal hospital, where she currently is. She is in need of an X-ray as well as stitches under anesthesia, all of which will come to about $1000- money I do not have, as the only working individual, and parent, that I am.

We are absolutely shaken, and heartbroken over tonights incident. I am asking my friends to donate whatever they can so that I may help Moscow. Please consider helping us.
