Hello snake friends! I’m a one week old snake mom and I just have a few small questions and a concern.

1. I see a lot of people say feed the snake in their enclosure. I’ve come to realize I have aspen bedding. (When the previous owner showed me the bedding he uses, all I saw was “snake bedding”) then later on here I saw that’s not the best bedding, I also saw a snake get sick from consuming it. My snake defidently swallowed some while he was eating the rat I fed him yesterday. Will he be okay? I had a nightmare he got sick ^^;
I also have paper bedding in as well (I added more in case he wanted to burrow) cause when I was at Walmart before I got him I wanted to pick up bedding, and I googled what to use and paper came up as one of the better things to use.

2. Do I need to find a specific vet for him if he needs to see a vet or do most vets treat snakes?

3. He eats medium size live rats, but my friend went to the pet store under the influence and bought a mouse thinking we could feed Mr. Noodles with it. Is there a chance of him taking interest in it? Is it worth feeding him since I won’t be able to handle him? And after and I fed him yesterday? How long should I wait if it’s okay to feed?

4. This one probably sounds stupid but I gotta know. I always hear that snakes can smell fear. Can they smell other feelings? At least the basic ones they can comprehend?

ALSO IM STILL LEARNING ABBREVIATIONS ON HERE.
