I'm in British Columbia, Canada. Weee lol.

I'd try and find a new bedding soon. It sounds like you are using pine. Pine has toxins called phenols, and when urine gets on the pine, the phenols are released into the air where your pet can breathe it in and damage it's respiratory system. It's even been shown to harm dogs. Cedar does the same thing, but it's worse because it also has microscopic spores that tear into the lungs and airways.
