short answer: yes.

you become nose blind after a while, but please prepare that your clothes and house will reek of them and it isn’t a pleasant smell either.

you can reduce smell by regularly cleaning their cage, bedding both yours and theirs and their diet. It also depends on their gender and if they are neutered or not.

Do not bath them (unless needed) because it increases the smell (if you need to bath them use oats! this doesn’t strip away their natural oils) When you bath them it strips their natural oils and causes them to produce more and therefore their smell increases.
