Long-tailed Chinchilla Chinchilla lanigera Class: Mammalia Order: Rodentia Family: Chinchillidae Characteristics: Body length 8 ½ -15 in. Tail Length 3-6 in. Sexually dimorphic- female 800g; male 500 g. Black-tipped fur, dense and soft – 60 hairs per follicle, more than any other mammal. Thick fur prevents water and heat loss. Tail furry with coarse hair. Head broad; external, large ears; black eyes; cheek pouches. Fore and hind foot have four digits with stiff bristles around weak claws. Excellent hearing helps to detect predators and long tail provides balance for high-speed escapes. Grasping forelimbs and sharp nails make for agile climbing. Endothermic. Behavior: Very Social. Have lived in colonies of over 100. Sit erect and hold the food in forepaws while eating. Can be hand-tamed to play and interact with owner. Primarily nocturnal with crepuscular activity peaks. Midday sun generally too hot but have been observed on sunny days sitting in front of holes, climbing and jumping on the rocks with amazing agility. Excessive heat escapes through large ears. Do not drink water but obtain it from dew on plants. Whiskers help navigate through cracks and fissures. Will express threats through growling, chattering teeth, and urination. Reproduction: Opportunistic breeders. As the dominant sex, females very aggressive during estrus. Breeding season is six months depending on hemisphere. 2-3 litters per year. After 112 days gestation, 2-4 precocial young, born fully furred with eyes open, will nurse 7-8 weeks, eat solid food at 2 weeks and mature sexually by 6 months. Diet: Wild: Birds eggs, insects, leaves, grains, nuts Zoo: Commercial Chinchilla Chow. Conservation: Critically endangered; only 10,000 left in wild. In addition to habitat destruction, although protected by law hunting for fur continues. Attempts at reintroduction into the wild have failed. Commercially bred animals are in no danger. FYI: AKA Chilean, coastal, common, or lesser chinchilla Considered to be the most valuable pelt in the world selling for as much as 100,000..

Chinchillas History the Chinchilla Is a Rodent Which Is Closely Related To
Chinchillas History The chinchilla is a rodent which is closely related to the guinea pig and porcupine. The pet chinchilla’s wild counterpart inhabits the Andes Mountain areas of Peru, Bolivia, Chile, and Argentina. In the wild state, they live at high altitudes in rocky, barren mountainous regions. They have been bred in captivity since 1923 primarily for their pelts. Some chinchillas that were fortunate enough to have substandard furs were sold as pets or research animals. Today chinchillas are raised for both pets and pelts. Chinchilla laniger is the main species bred today. They tend to be fairly clean, odorless, and friendly pets but usually are shy and easily frightened. They do not make very good pets for young children, since they tend to be high-strung and hyperactive (both children and chinchillas). The fur is extremely soft and beautiful bluish grey in color thus leading to their popularity in the pelt industry. Current color mutations include white, silver, beige, and black. Diet Commercial chinchilla pellets are available, but they are not available through all pet shops and feed stores. When the chinchilla variety is not in stock, a standard rabbit or guinea pig pellet can be fed in its place. Chinchillas tend to eat with their hands and often throw out a lot of pellets thus cause wastage. A pelleted formulation should constitute the majority of the animal’s diet. “Timothy”, or other grass hay, can be fed in addition to their pellets. Alfalfa hay is not recommended due to its high calcium content relative to phosphorus. Hay is a beneficial supplement to the diet for nutritional and psychological reasons.

Dwarf Hamster Care Sheet Because We Care !!!
Dwarf Hamster Care Sheet Because we care !!! 1250 Upper Front Street, Binghamton, NY 13901 607-723-2666 Congratulations on your new pet. Dwarf hamsters make good household pets as they are small, cute and easy to care for. Most commonly you will find Djungarian or Roborowski hamsters available. They are more social than Syrian (golden) hamsters and can often be kept in same sex pairs if introduced at a young age. Djungarian are brown or grey with a dark stripe down their back and furry feet. They grow to three to four inches in length and live up to two years. Roborowski hamsters are brown with white muzzle, eyebrows and underside. They grow to less than two inches long and live two to three years. GENERAL Give your new hamster time to adjust to its new home. Speak softly and move slowly so your hamster can learn to trust you. Put your hand in the cage and let the hamster smell you. In a short amount of time the hamster will recognize you and feel safe. Be sure to always wash your hands so you smell like you. Hamsters are naturally curios and can be encouraged to sit on your hand for a special treat. Cup your hands under and around the hamster so he feels safe, never squeeze or move suddenly and stay low to the floor so that if he jumps he won’t get injured. Dwarf hamsters tend to be less aggressive than standard hamsters and are frequently referred to as “no bite” hamsters. Keep in mind however that any animal will bite if frightened or injured.

Chinchilla Chinchilla
Spencer Murray BES 485 – Winter 2014 South American Wildlands Biodiversity Research and Communication Project The Chinchilla chinchilla A description of the Chinchilla chinchilla The Chinchilla chinchilla, also called the short-tailed chinchilla, is one of two species of chinchilla, which was previously known as Chinchilla brevicaudata until 1977 (Woods and Kilpatrick 2005). The species C. chinchilla has also called the Bolivian, Peruvian, and Royal chinchilla (Jiménez, 1996). It is about the size of a rodent and has, on average, a body that is heavier and longer than the other species of chinchilla, Chinchilla lanigera, although C. lanigera has a longer tail, which is why it is known as the long-tailed chinchilla. The C. chinchilla is gray in color, with a body similar to a squirrel, and large ears like a mouse. They have extremely plush fur with over 50 hairs per single follicle, (humans have one hair per follicle; Meadow, 1969). C. chinchilla has also been described as being about the size of a small rabbit with long soft fur (Grau, 1986), and a species that has one of the softest, longest, and finest furs of any wild mammal (Sage 1913; Walker 1968; Mann, 1978). *Side view photo of C. chinchilla: www.chinformation.com* Ecology of the C. chinchilla and its role in the ecosystem There is not much known about the ecology of the wild chinchilla, but what is known is that they live in colonies that can range from a few individuals to several hundred of the species (Mohlis, 1983). The C. chinchilla is a colonial species that feeds on vegetation and lives in rocky burrows or crevices in arid climates (IUCN Redlist: http://www.iucnredlist.org/details/4651/0).

Analysis of Morphological Variation of the Internal Ophthalmic Artery in the Chinchilla (Chinchilla Laniger, Molina)
Veterinarni Medicina, 60, 2015 (3): 161–169 Original Paper doi: 10.17221/8063-VETMED Analysis of morphological variation of the internal ophthalmic artery in the chinchilla (Chinchilla laniger, Molina) J. Kuchinka Institute of Biology, Jan Kochanowski University in Kielce, Kielce, Poland ABSTRACT: The aim of this investigation was the analysis of the variability within the internal and external ophthal- mic artery in the chinchilla (Chinchilla laniger, Molina). The head vasculature of 65 individuals was analysed, with particular emphasis on the internal ophthalmic artery originating from the central and rostral part of the cerebral arterial circle. Head blood vessels were filled with acrylic latex for vascular corrosion casting. The results showed ten variants of blood supply for the orbit, with a predominance of the first variant (66.1%) = bilateral presence of the external ophthalmic artery originating from the maxillary artery. Other variants differed in symmetry and asymmetry, sites of origination and the coexistence of both internal and external arteries. Vascularisation of the brain in chinchillas originates mainly from the vertebra-basilar system. The observed variability seems to confirm the role of the basilar artery in the arterial blood supply of the brain in this species. Keywords: variability; head arterial system; rodents The arterial system in the head of animals, in- rabbit Ruskell (1962).

Hamsters by Catherine Love, DVM Updated 2021
Hamsters By Catherine Love, DVM Updated 2021 Natural History Hamsters are a group of small rodents belonging to the same family as lemmings, voles, and new world rats and mice. There are at least 19 species of hamster, which vary from the large Syrian/golden hamster (Mesocricetus auratus), to the tiny dwarf hamster (Phodopus spp.). Syrian hamsters are the most popular pet hamsters, and also come in a long haired variety commonly known as “teddy bears”. There are numerous species of dwarf hamsters that may have multiple common names. The Djungarian dwarf (P. sungorus) is also sometimes called the “winter white dwarf” due to the fact that they may turn white during winter. Roborowski (Robo) dwarfs (P. roborovskii) are the smallest species of hamster, and also quite fast. The third type of dwarf hamster commonly kept is the Campbell’s dwarf (P. campbelli). Chinese or striped hamsters (Cricetulus griseus) can be distinguished from other species due to their comparatively long tail. The original pet and laboratory hamsters originated from a group of Syrian hamsters removed from wild burrows and bred in captivity. Wild hamsters are native to numerous countries in Europe and Asia. They spend most daylight hours underground to protect themselves from predators and are considered burrowing animals. While most wild hamster species are considered “Least Concern” by the IUCN, the European hamster is critically endangered due to habitat loss, pollution, and historical trapping for fur. Characteristics and Behavior Both Syrian and dwarf hamsters are very commonly found in pet stores. With gentle, consistent handling, hamsters can be tamed into fairly docile and easy to handle pets, but it is not uncommon for them to be bitey and skittish.

Chinchillas Are Crepuscular Rodents, Meaning That They Are Most Active During Dawn and Dusk
Warren Woods Veterinary Hospital 29157 Schoenherr Road Warren MI 48088 Telephone: 586-751-3350 Fax: 586-751-3447 www.wwvhcares.com Chinchillas: Care and Husbandry Chinchillas are crepuscular rodents, meaning that they are most active during dawn and dusk. Their bodies are about 10-14 inches long with a 5-6 inch tail and they have dense, soft fur. These adorable creatures are native to the Andes Mountains of Peru and Chile. The first chinchilla can be dated back to 1599. By the end of the 19th century they had become very rare due to people hunting them because of their soft fur. Chinchillas did not start becoming popular as pets until the 1960’s after being caught from the mountains and successfully bred. Chinchillas come in many colors. The most common is the standard gray. This is the only color found in nature. Other colors include beige, white, ebony, mosaic and numerous others. Chinchillas can make excellent pets. Just remember they are usually not very fond of being held and cuddled. If properly socialized from a young age they will be more tolerant of handling. They prefer to run, jump and play freely. Because of this they may not be the most appropriate pet for a young child. With the proper care a chinchilla may live to be 12-15 years old. Chinchillas cannot tolerate high temperatures (above 80 degrees Fahrenheit). Since they originated from the mountains they are accustomed to cooler temperatures and they cannot sweat. A chinchilla kept in temperatures above 80 degrees can overheat and may suffer from heat stroke.
