Respiratory disorders in cats are commonly diagnosed. Cats are known to develop chronic bronchitis, bronchial asthma and occasionally lung tumors. Respiratory diseases have many causes including bacterial, viral and fungal infections. In addition, it is known that airborne pollutants and dust particles can aggravate or initiate respiratory problems (17). Many occupational or industrial lung diseases in people are caused by inhaled dusts, including asbestos and silica (18). For example, one specific study suggests that there may be a relation between inhalation of a form of aluminum silicate and pulmonary fibrosis in workers who bagged this material for cat litter. (19). The clearance of these deposited particles from the lungs is by two major mechanisms: the mucociliary apparatus and the alveolar macrophage. Both of these mechanisms are impaired by silica dust deposition.
Note: I found World’s Best Cat Litter to be much dustier than SmartCat.
Here in the UK, we tried several different kinds before settling for wood-based (compressed pine sawdust pellets) litter. Solid waste is removed from the tray and flushed away before disposing of the rest, bagged in the empty plastic sacks the litter arrives in. The trays are cleaned every time with Petsafe disinfectant from the petshop. Ordinary household disinfectant is generally highly toxic for felines so we don’t have any in the house at all – we use Petsafe instead: it is more expensive but you don’t put a price on your cat’s safety, do you? That's very thoughtful of you to research this to save other people from breathing the litter dust. Now I just wish I had a cat to try it on!But stay away from those dusty litters! They are poison for you and your cats and really help make your home a Desperate for dusty cat litter solution I took some inspiration from the wood shop and it works like a charm. Lungs and house now dust free.
Cat litter dust has traditionally been a less pleasant partof cat ownership, but smart owners can reduce the amount of litter dustby using some readily available products.If your cat suddenly starts showing signs of allergies, such assneezing, coughing or if she refuses to use the litter box, change to adust-free litter. You might also have to switch to a ceramic or metallitter box, which are less likely to collect dust and dirt than plasticlitter boxes.The dust created by clay-based cat litter can pose a risk to bothcats and people. Cat owners have reported allergic or asthmaticreactions to the dust in both their pets and themselves. If yousuddenly develop allergic symptoms (such as sneezing, watery eyes orrunny nose), consult with an allergist to determine if you’re allergicto the litter dust or something else in your home. Ask another,non-allergic family member to handle the litter box cleaning choresuntil you and your doctor have determined the cause of your allergy.Another way to reduce the dust levels in your home is to use acovered litter box. Any dust kicked up by your cat’s scratching willstay in the box, rather than being circulated in the air. Adding an aircleaner or air filter to the room that contains the litter box can alsohelp reduce the amount of airborne dust.
