[15] [16] The data on the frequency of the disease in cats is contradictory, varying between 1.6 and 20%. [17] Chronic kidney disease occurs more frequently in older cats: Over 50% of affected cats are seven years old or older [ 17 ] and 30% of all cats over 9 years of age show elevated blood levels of nitrogen compounds ( azotemia ).

Aging in cats is the process by which cats change over the course of their natural lifespans. The normal lifespan of domestic cats is in the range of 13 to 20 years. As cats senesce, they undergo predictable changes in health and behavior. Dental disease and loss of olfaction are common as cats age, affecting eating habits.
Neutropenia is an abnormally low concentration of neutrophils (a type of white blood cell) in the blood. [4] Neutrophils make up the majority of circulating white blood cells and serve as the primary defense against infections by destroying bacteria, bacterial fragments and immunoglobulin-bound viruses in the blood.

There are five (HNA 1–5) sets of neutrophil antigens recognized. The three HNA-1 antigens (a-c) are located on the low affinity Fc-γ receptor IIIb (FCGR3B :CD16b) The single known HNA-2a antigen is located on CD177. The HNA-3 antigen system has two antigens (3a and 3b) which are located on the seventh exon of the CLT2 gene .
Autoimmune neutropenia (AIN) is a form of neutropenia which is most common in infants and young children [1] where the body identifies the neutrophils as enemies and makes antibodies to destroy them. Primary autoimmune neutropenia, another name for autoimmune neutropenia, is an autoimmune disease first reported in 1975 that primarily occurs in ...
Feline diseases are often opportunistic and tend to be more serious in cats that already have concurrent sicknesses. Some of these can be treated and the animal can have a complete recovery. Others, like viral diseases, are more difficult to treat and cannot be treated with antibiotics, which are not effective against viruses.
Neutropenia indicates a deficiency of neutrophils (the most common granulocyte cell) only. [ citation needed ] To be precise, neutropenia is the term normally used to describe absolute neutrophil counts (ANCs) of less than 500 cells per microlitre, whereas agranulocytosis is reserved for cases with ANCs of less than 100 cells per microlitre.
Cats may be poisoned by many chemicals usually considered safe by their human guardians, [citation needed] because their livers are less effective at some forms of detoxification. [31] [32] Some of the most common causes of poisoning in cats are antifreeze and rodent baits. [33] Cats may be particularly sensitive to environmental pollutants. [34]
