I was bitten by a squirrel, just a little?

I would definitely either go to the doctor and get the whole rabies treatment or just bring the squirrel in to be tested for it. They would have to kill the squirrel, so if for some reason you really don't want that to be done, then just go and get the vaccinations. Rabies is an extremely serious disease that is almost always fatal, so it's better to be safe than sorry. I actually just started my first dose of the shots today because there was a bat flying around in my house for a while (though it never bit me). I wasn't able to capture the bat so the doctor said I had to be treated regardless of whether I really had it or not. You don't get injected through the abdomen any longer with these shots, so if you have heard bad things in the past about them you shouldn't worry. You do have to get a lot of shots though, like 8-9 on four days throughout a period of like 2 weeks, so if at all possible, I would just try to bring the squirrel in to be tested so that you could have a chance at averting all of the inconvenience.
