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.
The name Pearl is taken from the gemstone, like the earring worn by the girl in the portrait The Girl with a Pearl Earring by Jan Vermeer. Pearl is a primarily feminine given name derived from the English word pearl, a hard, roundish object produced within the soft tissue of a living, shelled mollusk. Pearls are commonly used in jewelry-making. The pearl is the birthstone for the month of June. Pearls have been associated with innocence and modesty.
