* Dander is constantly shed: Even while a cat is alive, dander is constantly being shed and replaced.
* Environmental factors: How long dander lingers depends on factors like:
* Ventilation: Well-ventilated areas will clear dander more quickly.
* Cleaning: Regular vacuuming and cleaning will help remove dander.
* Surface type: Dander may cling to certain surfaces longer than others.
* Decomposition: As the cat's body decomposes, dander will be broken down along with other organic matter.
What you can do:
* Thorough cleaning: After a cat passes away, it's crucial to thoroughly clean the areas where the cat spent time. Vacuuming with a HEPA filter is especially helpful.
* Focus on high-traffic areas: Pay close attention to furniture, bedding, and areas where the cat often rested.
* Professional cleaning: Consider hiring a professional cleaning service if you have concerns about allergy triggers.
Remember: Even after cleaning, some trace amounts of dander might still remain. If you have allergies, consult with your doctor or allergist about how to manage them.
