The rat ate my snake!

[Hexis]

I had left a rat over night in the cage with my snake hoping it would get around to eating it. I thought nothing of it because I have done this many times before. When I woke up the next morning I saw to my horror that the rat had eaten two huge holes on either side of its tale (right above the cloaca)! After freaking out for about 10 minutes I took the snake to a vet which they kept the snake for 5 days and tried to stitch up the holes in the snake. The snake did not bite the rat in defense due to a infection in the front of its mouth (I had schedule an appointment for that later that week). They gave me several things to take home with me to give to the snake. Meloxicam, a pain killer which I had to get the snake to swallow, Fortaz, a antibiotic that needs to be injected with a syringe, and Chlorhexiderm a disinfectant to clean the wound. I had the snake home for about 10 days before I brought it back in for a check up. They tube fed the snake and removed one side of the stitches because they were not holding. The hole on the side of the snake worries me. Do you guys think the hole will be able to close itself up? The vet not really sure, they said they might make another attempt at it a few weeks from now, but until then to just keep it as clean as possible. Yeah I know I am an idiot for letting this happen, but the way I had been feeding it seem to be working out fine for the last 3 years. This was such a horrific shock to me that I didn’t go to sleep for 2 days! Has anyone heard of anything happening like this? The following picture only shows one side of the tail, the other side is still stitched up, ill post a pic of that if anyone is interested.

I feel incredibly bad for letting this happen!
