Paint - We have not tested the paint in the apartment for lead but there has been no painting done since we moved in.
Air Fresheners - We only use Febreeze and we don't use it in the snake room. We have used it once in the snake room since moving in and it was only applied to a blanket we have under the ferret cage, never near the racks or in the air. (and it was only a couple days ago)
Parasites - There are no visible signs of external parasites. When I speak to the vet I will see about getting a fecal done, though she has no fecal matter to pass yet. Not sure how long a pinkie takes to digest, but she should have some poo when that is done.
I'm weighing all of my snakes today, and all weights are on the rise, save for the babies that are not eating.
