I Think My BP has RI

I do believe that may be a case for a vet.

All the symptoms together could very well mean Upper Respiratory Infection. They can also do all this while in shed, but then you would have noticed him going through some of the shed cycle.

The non eating would be mostly due to being sick, but eventually you may have to tweak your setup a bit to entice him. Can you post a picture of it? Seems you are on top of the temps and humidity and that is very good !!! Now you have to make sure you have a very private setup, not wide open. For example, black out the sides and back by taping construction paper or something on the outside of them. Make sure the hides are small enough, and have identical ones on warm and cold side. Clutter it up some.

If you have to treat for an illness, you may actually have to set up a "quarantine/sick tub". They are smaller and easier to keep sanitized. If you cannot do that, you will have to remove everything out of your cage, esp. substrate and extra deco (for now). You need to keep a sick snake on paper towels, something you can clean and sanitize daily. You don't want to keep deco, unless its the kind that can be sanitized.

Since the cage will need to be rather "bare" make sure the sides and back are blacked out, the top mostly covered, and a few hides throughout. Easy to clean hides.

The rest will be up to you and the vet.

Petco snakes aren't ideal, like from most big box store, but it is what it is. You have the lil one now and kudos for doing the right thing

Good luck, and keep us up to date..
