1 In dogs, cetirizine is used primarily to treat allergic symptoms and itchy skin e.g from allergic dermatitis and atopy in dogs.  In cats, cetirizine is used to treat non-responsive chronic inflammation of the nose and sinuses (rhinosinusitis). It is also used to treat pruritus (itching) in cats.
Mother of pearl, also called nacre, is an iridescent layer of material that forms the shell lining of many mollusks. Pearl oysters and abalone are both sources of this substance, which is widely used as an inlay in jewelry, furniture, and musical instruments.
Because of its subtle sheen and iridescent colors, mother of pearl has never fallen out of fashion. Not only was it used for making jewelry, it has also been used for creating beautiful boxes, forming mosaics, and fashioning carvings. Throughout history, mother of pearl has been a favorite with people the world over.
