Bad Gash! What to do until vet visit?

[Sita]

You could do Betadine treatments twice a day, and apply neosporin once a day. Dilute the Betadine to a light tea color and soak the spot for about 5 minutes. Pat dry with paper towels, and apply a very small amount of neosporin. Make sure it does NOT have any pain relievers in it, as snakes can have severe reactions to it. Bacitracin by itself isn't a pain reliever, that's something added in, usually Pramoxine, or ending with -caine. You can find Betadine in the first aid section of Walgreens or Walmart, near the hydrogen peroxide. You will also want to clean out the cage thoroughly and use only paper towels as substrate in order to prevent infection.

You don't want to use neosporin for longer than the few days until the vet, as it can soften and damage the scales.

I also highly recommend separating your snakes. You are risking the very LIFE of both of snakes by housing them together, especially the little one. The larger one might one day decide to kill Perry for no reason, and if one gets sick, you're going to be spending twice as much at the vet to treat both animals. Not to mention the fact that if Dino and Perry are definitely male and female, if Perry becomes gravid too soon, she could easily die from complications.

Like Nikki (satomi) said, Ball Pythons are solitary animals, and do not "enjoy" each others company. An argument some people use is that they see them "cuddling", but that is not what they are doing. They are actually competing for the same resources, which is stressful for them, and a stressed snake gets sick much more easily.

Just some things to think about and consider. Keep us updated on the wound and vet visit please!
