Kitten
A kitten is a Juvenile (organism), juvenile cat. After being born, kittens display primary altriciality and are fully dependent on their mothers for #Establishing immunity, survival. They normally do not open their eyes for seven to ten days. After about two weeks, kittens develop quickly and begin to explore the world outside their nest. After a further three to four weeks, they begin to eat solid food and grow baby teeth. Domestic kittens are highly social animals and usually enjoy human companionship. Etymology The word "kitten" derives from the Middle English word , which in turn came from the Old French or . Juvenile big cats are called "cubs" rather than kittens; either term (but usually more commonly "kitten") may be used for the young of smaller wild felidae, felids, such as ocelots, caracals, and lynxes. Development A feline Litter (animal), litter usually consists of two to five kittens, but litters with one to more than ten are known. Kittens are typically born af ...

Weaning
Weaning is the process of gradually introducing an infant human or other mammal to what will be its adult diet while withdrawing the supply of its mother's milk. In the United Kingdom, UK, weaning primarily refers to the introduction of solid foods at 6 months; in the United States, US, it primarily refers to stopping breastfeeding. The process takes place only in mammals, as only mammals produce milk. The infant is considered to be fully weaned once it is no longer breastfeeding, fed by any breast milk (or bottled Infant formula, substitute). Humans In some cultures, weaning progresses with the introduction of feeding the child food that has been prechewed by the parent along with continued breastfeeding, a practice known as premastication. The practice was important throughout human history in that it naturally gave a child a greatly improved protein source in addition to preventing iron deficiency. However, premasticated food from caregivers of lower socioeconomic status i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feline Panleukopenia
''Carnivore protoparvovirus 1'' is a species of parvovirus that infects carnivorans. It causes a highly contagious disease in both dogs and cats separately. The disease is generally divided into two major genogroups: the group of the classical feline panleukopenia virus (FPLV), and the group of the canine parvovirus type 2 (CPV-2), which appeared in the 1970s. Belonging to the family Parvoviridae, FPLV have linear, single-stranded DNA (ssDNA) genomes. This agent is one of the smallest animal viruses, barely 18 to 20 nm in diameter. Like other parvovirus genomes, it has hairpin structures at both ends of its genome: 3-genome Y-type structure and 5-terminal U-shaped structure, making it challenging to amplify the full-length genome of parvovirus despite its small size. Sequences in the genome show a high degree of nucleotide conservation in the VP2 gene after over 90 years since it has emerged; the VP2 gene codes for the capsid protein VP2, a main structural protein, which det ...

Ocelot
The ocelot (''Leopardus pardalis'') is a medium-sized spotted Felidae, wild cat that reaches at the shoulders and weighs between on average. It is native to the southwestern United States, Mexico, Central America, Central and South America, and the Caribbean islands of Trinidad and Margarita Island, Margarita. Carl Linnaeus scientific description, scientifically described it in 1758. Two subspecies are recognized. The ocelot is efficient at climbing, leaping and swimming. It prefers areas close to water sources with dense vegetation cover and high prey availability. It preys on small terrestrial mammals, such as armadillos, opossums, and lagomorphs. It is typically active during twilight and at night and tends to be solitary and Territory (animal), territorial. Both sexes become sexual maturity, sexually mature at around two years of age and can breed throughout the year; peak mating season varies geographically. After a gestation period of two to three months, the female giv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caracal
The caracal (''Caracal caracal'') () is a medium-sized Felidae, wild cat native to Africa, the Middle East, Central Asia, and arid areas of Pakistan and northwestern India. It is characterised by a robust build, long legs, a short face, long tufted ears, relatively short tail, and long canine teeth. Its coat is uniformly reddish tan or sandy, while the ventral parts are lighter with small reddish markings. It reaches at the shoulder and weighs . It was first scientific description, scientifically described by German naturalist Johann Christian Daniel von Schreber in 1776. Three subspecies are recognised. Typically nocturnality, nocturnal, the caracal is highly secretive and difficult to observe. It is territory (animal), territorial, and lives mainly alone or in pairs. The caracal is a carnivore that typically preys upon birds, rodents, and other small mammals. It can leap higher than and catch birds in midair. It stalks its prey until it is within of it, after which it ru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feline Vaccination
Feline vaccination is animal vaccination applied to cats. Vaccination plays a vital role in protecting cats from infectious diseases, some of which are potentially fatal. They can be exposed to these diseases from their environment, other pets, or even humans. Principles guiding vaccination recommendations The practice of recommending and giving vaccines on a fixed schedule with annual boosters has been widely discarded. Current recommendations are based on the philosophy of vaccinating each cat no more frequently than necessary. These recommendations take into account considerations for the efficacy and duration of immunity (DOI) of available vaccines; environmental risks and likelihood of exposure; the specific needs and risks associated with age and overall health status of different cats and cat populations; and socioeconomic limitations. Recommendation vary for: * Shelters * Owned pets (and based on "inside only", "in and out", or "out only") * Breeders * Boarding faciliti ...

Feline Calicivirus
Feline calicivirus (FCV) is a virus of the family ''Caliciviridae'' that causes disease in cats. It is one of the two important viral causes of respiratory infection in cats, the other being feline herpesvirus. FCV can be isolated from about 50% of cats with upper respiratory infections. Cheetahs are the other species of the family Felidae known to become infected naturally. Viral structure and pathogenesis Different strains of FCV can vary in virulence (the degree of pathogenicity within a group or species of microorganisms or viruses as indicated by case fatality rates and/or the ability of the organism to invade the tissues of the host). Being an RNA virus, FCV has a high elasticity of its genome, which makes it more adaptable to environmental pressures. This not only makes the development of vaccines more difficult, but also allows for the development of more virulent strains. In persistently infected cats, the gene for the major structural protein of the viral capsi ... [...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 ...

Lynx
A lynx ( ; : lynx or lynxes) is any of the four wikt:extant, extant species (the Canada lynx, Iberian lynx, Eurasian lynx and the bobcat) within the medium-sized wild Felidae, cat genus ''Lynx''. The name originated in Middle English via Latin from the Greek word (), derived from the Indo-European root (, ), in reference to the luminescence of its tapetum lucidum, reflective eyes. Appearance Lynx have a short tail, characteristic tufts of black hair on the tips of their ears, large, padded paws for walking on snow and long whiskers on the face. Under their neck, they have a ruff, which has black bars resembling a bow tie, although this is often not visible. Body colour varies from medium brown to goldish to beige-white, and is occasionally marked with dark brown spots, especially on the limbs. All species of lynx have white fur on their chests, bellies and on the insides of their legs, fur which is an extension of the chest and belly fur. The lynx's colouring ...

Juvenile (organism)
A juvenile is an individual organism (especially an animal) that has not yet reached its adult form, sexual maturity or size. Juveniles can look very different from the adult form, particularly in colour, and may not fill the same niche as the adult form. In many organisms the juvenile has a different name from the adult (see List of animal names). Some organisms reach sexual maturity in a short metamorphosis, such as ecdysis in many insects and some other arthropods. For others, the transition from juvenile to fully mature is a more prolonged process—puberty in humans and other species (like higher primates and whales), for example. In such cases, juveniles during this transformation are sometimes called subadults. Many invertebrates cease development upon reaching adulthood. The stages of such invertebrates are larvae or nymphs. In vertebrates and some invertebrates (e.g. spiders), larval forms (e.g. tadpoles) are usually considered a development stage of their own, an ...

Hypothermia
Hypothermia is defined as a body core temperature below in humans. Symptoms depend on the temperature. In mild hypothermia, there is shivering and mental confusion. In moderate hypothermia, shivering stops and confusion increases. In severe hypothermia, there may be hallucinations and paradoxical undressing, in which a person removes their clothing, as well as an increased risk of the heart stopping. Hypothermia has two main types of causes. It classically occurs from exposure to cold weather and cold water immersion. It may also occur from any condition that decreases heat production or increases heat loss. Commonly, this includes alcohol intoxication but may also include low blood sugar, anorexia and advanced age. Body temperature is usually maintained near a constant level of through thermoregulation. Efforts to increase body temperature involve shivering, increased voluntary activity, and putting on warmer clothing. Hypothermia may be diagnosed based on either a ...

Altriciality
Precocial species in birds and mammals are those in which the young are relatively mature and mobile from the moment of birth or hatching. They are normally nidifugous, meaning that they leave the nest shortly after birth or hatching. Altricial species are those in which the young are underdeveloped at the time of birth, but with the aid of their parents mature after birth. These categories form a continuum, without distinct gaps between them. In fish, this often refers to the presence or absence of a stomach: precocial larvae have one at the onset of first feeding whereas altricial fish do not. Depending on the species, the larvae may develop a functional stomach during metamorphosis (gastric) or remain stomachless (agastric). Precociality Precocial young have open eyes, hair or down, large brains, and are immediately mobile and somewhat able to flee from or defend themselves against predators. For example, with ground-nesting birds such as ducks or turkeys, the young are rea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retina
The retina (; or retinas) is the innermost, photosensitivity, light-sensitive layer of tissue (biology), tissue of the eye of most vertebrates and some Mollusca, molluscs. The optics of the eye create a focus (optics), focused two-dimensional image of the visual world on the retina, which then processes that image within the retina and sends nerve impulses along the optic nerve to the visual cortex to create visual perception. The retina serves a function which is in many ways analogous to that of the photographic film, film or image sensor in a camera. The neural retina consists of several layers of neurons interconnected by Chemical synapse, synapses and is supported by an outer layer of pigmented epithelial cells. The primary light-sensing cells in the retina are the photoreceptor cells, which are of two types: rod cell, rods and cone cell, cones. Rods function mainly in dim light and provide monochromatic vision. Cones function in well-lit conditions and are responsible fo ...
