Luna's Medical Bill

My wonderful cat luna was sitting on the porch having a nap when a stray dog came up and pulled him off the porch. I managed to get outside and break it up but Luna suffered a broken rib, fluid in his lungs, and possible spinal injury. He's currently being held at the veterinary office for 2 days on IV fluid, steriods, and anti-biotics. The total cost as of right now is $300 for xrays and continued treatment. Any donation towards this would be greatly appreciated. Luna is a very relaxed and friendly cat happy to make friends with anyone who would give him a little bit of attention. He means the world to me and has been with me for 7 years now. I don't want to lose him simple because I can't afford to treat him. This would mean the world to me to have him healthy and back at home.
