If you're in a pinch, use a 28 or 32 qt underbed storage bin with a tight fitting and secure top. It'll cost you 10 bucks. Get a heat pad and make sure it's got a thermostat properly regulating it! A cheap one you can get rush shipped is http://www.amazon.com/Hydrofarm-MTPR.../dp/B000NZZG3S If you have an area of your house over 75 degrees it can probably live in the bin without the heat pad until that thermostat and a heat pad arrives / can be bought.
If it has burns it needs to go on paper towels until you can get it to a vet. They're going to give you silver sulfadiazine cream. Unfortunately it isn't over the counter. After it heals a bit, you can try feeding.
