So I was at a friends while he was doing cage cleaning and he took one of his female rhino rats out and I of course wanted to admire it and all was fine, then I decided to try to pet on the head and it didn't like that very much. So here was the result:
Let me say that an adult female packs a punch for a rat snake. Then my hands are sensitive so it was moving it's head digging in the teeth. Then I thought it was trying to get off my finger after like 10 minutes because I felt it going down but it turns out that it was going towards the tip to try to swallow my finger. That was not fun trying to get it off, especially since the water trick don't work on them.
