How often should I change out cat litter to maintain a clean and healthy environment for my feline companion? Is there a definitive timeline that I should adhere to, or does the frequency depend on specific factors such as the type of litter I use and the number of cats I have? Could the unique habits and behaviors of my cat, such as whether they prefer to urinate or defecate in one corner of the litter box, influence how quickly the litter becomes soiled? Furthermore, might external conditions, like temperature and humidity levels, also play a role in the litter’s longevity? Is there a recommended method for assessing when a change is necessary? Should I be looking for signs such as odor intensity or visible clumps forming? In considering the well-being of my pet, what other considerations are essential in determining how often to replace litter effectively?
