Bleach
Bleach is not the best ingredient when it comes to human health either, but you can imagine just how much worse it is for your furry friends, who are even more sensitive to the elements than we are.
When it comes to bleach, the pungent smell is going to disturb them by default, and due to how hypersensitive their sense of smell is, the scent of bleach is more likely than not to irritate their noses. In the long run, if they keep inhaling bleach fumes, they can develop breathing issues.
What’s more, it can get even worse if they somehow end up eating bleach.
