So I heard a strange noise from my ball python's cage and went in to find him with the duct tape I use to attach his temp probe wrapped around his neck. I freaked out and removed the tape with some mineral oil but it looks like there's some scales missing. There's also red patches like there's blood underneath his scales as well as the skin between his scales. I have learned my lesson with not putting duct tape in his cage I'm wanting to know how bad the damage looks to you guys and if it warrants a vet visit. He was a little skittish once I got the tape off but now he seems fine and is moving around like usual.
