Feline Corneal Sequestrum
Feline corneal sequestrum (also known as feline corneal necrosis) is the development of dark areas of dead tissue in the cornea of domestic cats. This disease is painful to the cat, although it develops slowly over a longer period of time. Cats will usually demonstrate teary eye(s), squinting or closing of the eye(s), and covering of the third eyelid. Presentation The affected area of the cornea develops a brown discoloration. The area surrounding the sequestrum may have superficial ulceration. The corneal sequestrum is painful, and the cat may show this by squinting or closing the eye (blepharospasm). Causes The cause of corneal sequestra is unknown. A sequestrum in the cornea usually develops following long term (chronic) ulceration of the cornea. Feline viral rhinotracheitis (previously known as Feline herpes virus) is often found in cats with a corneal sequestrum. Prevention As the cause is not known, it is difficult to know what steps to take to prevent this from occurr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dead Tissue
Death is the end of life; the Irreversible process, irreversible cessation of all biological process, biological functions that sustain a living organism. Death eventually and inevitably occurs in all organisms. The remains of a former organism normally begin to Decomposition, decompose shortly after death. Some organisms, such as ''Turritopsis dohrnii'', are Biological immortality, biologically immortal; however, they can still die from means other than Senescence, aging. Death is generally applied to whole organisms; the equivalent for individual components of an organism, such as Cell (biology), cells or Tissue (biology), tissues, is necrosis. Something that is not considered an organism, such as a virus, can be physically destroyed but is not said ''to die'', as a virus is not considered alive in the first place. As of the early 21st century, 56 million people die per year. The most common reason is aging, followed by cardiovascular disease, which is a disease that af ...

Cornea
The cornea is the transparency (optics), transparent front part of the eyeball which covers the Iris (anatomy), iris, pupil, and Anterior chamber of eyeball, anterior chamber. Along with the anterior chamber and Lens (anatomy), lens, the cornea Refraction, refracts light, accounting for approximately two-thirds of the eye's total optical power. In humans, the refractive power of the cornea is approximately 43 dioptres. The cornea can be reshaped by surgical procedures such as LASIK. While the cornea contributes most of the eye's focusing power, its Focus (optics), focus is fixed. Accommodation (eye), Accommodation (the refocusing of light to better view near objects) is accomplished by changing the geometry of the lens. Medical terms related to the cornea often start with the prefix "''wikt:kerat-, kerat-''" from the Ancient Greek, Greek word κέρας, ''horn''. Structure The cornea has myelinated, unmyelinated nerve endings sensitive to touch, temperature and chemicals; a to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Domestic Cats
The cat (''Felis catus''), also referred to as the domestic cat or house cat, is a small domesticated carnivorous mammal. It is the only domesticated species of the family Felidae. Advances in archaeology and genetics have shown that the domestication of the cat occurred in the Near East around 7500 BC. It is commonly kept as a pet and working cat, but also ranges freely as a feral cat avoiding human contact. It is valued by humans for companionship and its ability to kill vermin. Its retractable claws are adapted to killing small prey species such as mice and rats. It has a strong, flexible body, quick reflexes, and sharp teeth, and its night vision and sense of smell are well developed. It is a social species, but a solitary hunter and a crepuscular predator. Cat intelligence is evident in their ability to adapt, learn through observation, and solve problems. Research has shown they possess strong memories, exhibit neuroplasticity, and display cognitive skills compara ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blepharospasm
Blepharospasm is a neurological disorder characterized by intermittent, involuntary spasms and contractions of the orbicularis oculi muscle, orbicularis oculi (eyelid) muscles around both eyes. These result in abnormal twitching or blinking, and in the extreme, sustained eyelid closure resulting in functional blindness. The word blepharospasm is derived from the Greek: βλέφαρον / blepharon, eyelid, and σπασμός / spasmos, ''spasm,'' an uncontrolled muscle contraction. The condition should be distinguished from the more common, and milder, involuntary quivering of an eyelid, known as myokymia or fasciculation. Blepharospasm is one form of a group of movement disorders called dystonia. It may be a primary or secondary disorder. The primary disorder is benign essential blepharospasm, in which term the qualifier ''essential'' indicates that the Idiopathic, cause is unknown. Blepharospasm may occur as secondary to conditions including dry eyes and other specific ocul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feline Viral Rhinotracheitis
Feline viral rhinotracheitis (FVR) is an upper respiratory or pulmonary infection of cats caused by Feline herpesvirus, also called Feline herpesvirus 1 (FeHV-1), of the family '' Herpesviridae''. It is also commonly referred to as feline influenza, feline coryza, and feline pneumonia but, as these terms describe other very distinct collections of respiratory symptoms, they are misnomers for the condition. Viral respiratory diseases in cats can be serious, especially in catteries and kennels. Causing one-half of the respiratory diseases in cats, FVR is the most important of these diseases and is found worldwide. The other important cause of feline respiratory disease is '' feline calicivirus''. FVR is very contagious and can cause severe disease, including death from pneumonia in young kittens. It may cause flat-chested kitten syndrome, but most evidence for this is anecdotal. All members of the family Felidae are susceptible to FVR; in fact, FHV-1 has caused a fatal encepha ...

Persian Cat
The Persian cat, also known as the Persian Longhair, is a long-haired breed of cat characterised by a round face and short muzzle. The first documented ancestors of Persian cats might have been imported into Italy from Greater Khorasan, Khorasan as early as around 1620, but this has not been proven. Instead, there is stronger evidence for a longhaired cat breed being exported from Afghanistan and Iran, Iran/Persia from the 19th century onwards. Persian cats have been widely recognised by the North-West European Cat culture, cat fancy since the 19th century, and after World War II by breeders from North America, Australia and New Zealand. Some cat fancier organisations' breed standards subsume the Himalayan cat, Himalayan and Exotic Shorthair as variants of this breed, while others generally treat them as separate breeds. The selective breeding carried out by breeders has allowed the development of a wide variety of coat colours, but has also led to the creation of increasingly ...

Exotic Shorthair
The Exotic Shorthair is a breed of cat developed as a short-haired version of the Persian. The Exotic is similar to the Persian in appearance with the exception of the short dense coat. History In the late 1950s, the Persian was used as an outcross by some American Shorthair breeders. This was done in secret in order to improve their body type, and crosses were also made with the Russian Blue and the Burmese. The crossbreed look gained recognition in the show ring, but unhappy American Shorthair breeders successfully produced a new breed standard that would disqualify American Shorthairs that showed signs of crossbreeding. One American Shorthair breeder who saw the potential of the Persian/American Shorthair cross proposed and eventually got the Cat Fanciers' Association judge and American Shorthair breeder Jane Martinke to recognize them as a new breed in 1966, under the name Exotic Shorthair. In 1987, the Cat Fanciers' Association closed the Exotic to shorthair outcross ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Himalayan Cat
The Himalayan (short for Himalayan Persian, or Colourpoint Persian as it is commonly referred to in Europe), is a breed or sub-breed of long-haired cat similar in type to the Persian cat, Persian, with the exception of its blue eyes and its point colouration, which were derived from crossing the Persian with the Siamese cat, Siamese. Some registries may classify the Himalayan as a long-haired sub-breed of Siamese, or a colourpoint sub-breed of Persian. The World Cat Federation has merged them with the Colorpoint Shorthair, Colourpoint Shorthair and Javanese cat, Javanese into a single breed, the Colourpoint. History Work to formally establish a breed with combined Persian and Siamese traits, explicitly for the cat fancy, began in the United States in the 1930s at Harvard University, under the term Siamese–Persian, and the results were published in the ''Journal of Heredity'' in 1936, First page is available online at http://jhered.oxfordjournals.org/cgi/pdf_extract/27/9/3 ...
