Moulting behaviours?

[Squiggles:D]

Just wondering if most of these are normal because I'm starting to think that a vet appointment isn't incredibly urgent (like I could make it in a few weeks) and it's just because he's moulting. If any of these aren't normal I will make an urgent vet appointment.
Things he's been doing:
-aggressive/hormonal
-excessive sneezing
-constantly scratching the face
-tail chewing (?)

P.S there is no liquid with his sneezes, and his nose is not irritated or blocked, it’s just a dry sneeze

Is there a lot of dust in your home?

What region of this huge World effects how to answer this question.
Sounds like molting and that the number of baths may need to be increased.
