There are 24 species of hamsters, according to the Universities Federation for Animal Welfare , and these animals come in a wide range of sizes. The European breed can grow as large as 12.5 inches long and are some of the biggest varieties of hamsters, according to the journal Biomarkers in Toxicology .

The dwarf hamster lives up to its name. These tiny hamsters grow to around 2 to 4 inches long, according to AZ animals . The most common pet hamster, the Syrian hamster, also known as the teddy bear hamster or golden hamster, usually grows to about 6 inches long.

Intersexual Aggression And Cannibalism

Female Chinese and Syrian hamsters are known for being aggressive toward males if kept together for too long after mating. In some cases, male hamsters can die after being attacked by a female. If breeding hamsters, separation of the pair after mating is recommended, or they will attack each other.

Female hamsters are also particularly sensitive to disturbances while giving birth, and may even eat their own young if they think they are in danger, although sometimes they are just carrying the pups in their cheek pouches. If captive female hamsters are left for extended periods with their litter, they may cannibalize the litter, so the litter must be removed by the time the young can feed and drink independently.

Benign And Malignant Tumors

Two types of tumors appear in the hamsters. One is malignant, and the second one is a benign tumor. Benign is not dangerous, and it will affect your hamster a little bit. Benign tumors are overgrown cells. These cells do not move from one place to another place of the body. If a lump grows on the hand of your hamster and it grows in a specific size and then it stops growing, it is benign.

In other words, a lump that grows on a certain part of the body, then it stops growing, and it does not cause more lumps on the different parts of the body then this tumor is benign.

Malignancy is dangerous, and it will severely affect the health of your hamster. It can spread to the other areas of the body. It also means that if it grows on the hand of the hamster, then it will grow on the shoulder, and if it grows on the leg of the hamster, then it will grow on his belly.

Just take your hamster to him he will examine your hamster. And he will tell you what the possible solution is. The Vet will collect some samples, and he will study all the samples. Maybe the Vet will do an x-ray of your hamster. And after all this process, he will tell you that your hamster is in danger or not.

Food What Do Syrian Hamsters Eat

When it comes to your pet Syrian hamsters nutrition, you should base their diet on a high-quality commercial hamster mix. There is a huge range of brands, and it can be a daunting task choosing your hamster food.

A good hamster mix should contain a right combination of seeds, grains, and nuts with nutritional balance of roughly 12-15% protein and 3-6% fat. Pregnant hamsters should get extra protein and fat while they are expecting and nursing.

You can supplement your hamster with fresh fruit and vegetables. Favorites include Applies, Carrots, Broccoli, Pears, and Cabbage. Avoid citrus fruits as they are too acidic.

You should make sure not to feed fresh food every day because hamsters like to hoard food in their nests. Excess fruit and veg can also cause stomach upsets and diarrhea. Wash any food to remove any pesticides harmful to your pet. Be sure to remove any uneaten fresh food after 24 hours to prevent them from eating spoiled food.

All species of hamsters have cheek pouches which, in the wild are used to transport food into their burrow. Hamster owners often mistakenly judge their hamsters food intake because they do not take into account the food that has been hoarded away!

Repetitive Exposure To Partners Cage

Clinical anatomy of the European hamster, Cricetus cricetus, L.

The purpose of placing each male in his partners cage daily was to reduce the effects of handling and exposure to another males odors on the responsiveness of the HPA axis. This goal was met, because plasma glucocorticoids and c-fos expression within the PVN were not significantly different between UHC and HC males.

Although the HC group did not show a stress response, these males did possess activation in numerous brain areas. Some of the most striking changes occurred in brain regions that process chemosensory cues including the mitral and granule cell layers of the AOB and MOB, and many of their central targets: amygdaloid nuclei and Pir cortex. Additional brain regions showed increased activation after handling including: Cg and LO cortices, lateral septum, anterior subdivisions of BNST, BLa, several hypothalamic nuclei , hippocampus, dorsal PAG, and cuneiform nucleus. It is likely that the specific functions mediated by activation within these various brain regions vary however, these data indicate that behavioral arousal is associated with increased activation throughout the brain.

Patterns Common Fur Patterns Of Syrian Hamsters

Banded A very typical pattern found at pet stores and breeders, a banded hamster typically has a band of white fur around their mid-section. Most color variations can have the band trend. The band width is variable.

Dominant Spot In 1964 the dominant spot was first discovered in the USA and rapidly became more popular than the piebald because it was easy to breed. By UK and US standards, this hamster is commonly described as a white hamster with colored spots.

Piebald Another familiar pattern you will most likely find in pet stores, the piebald hamster has a colored coat dotted with white spots all over. The spots can be small and few or can cover the whole body. Piebalds can sometimes have bellies with different color as well. Piebalds are difficult to breed and are considered to be close to extinction by some in the hamster community.

Tortoiseshell Tortoiseshell hamsters are two colored animals with two primary color tones in their coat. One of these colors is always yellowy, and the patches are distinct with no bridling. Only female hamsters can be the tortoiseshell variant because the gene is linked to the female sex.

Tortoiseshell and White The same as a tortoiseshell except they have a white band and a white belly. Again, females can only be this variant because of the female-linked gene.

Roan Roan hamsters look very similar to white hamsters, but they have coloration splattered around the head area which gradually dissipates towards the rear.

Treats Treating Your Syrian Hamster

You can give your hamster treats once or twice a week to provide some extra protein. Hamsters love treats, but you should not over feed them. Sugar-Filled shop bought treats such as honey sticks are often very unhealthy in large quantities. Some examples of healthier treats to feed your hamster includes

  • Some hard boiled egg white
  • Cottage Cheese
  • Small amounts of Timothy hay
  • Sunflower Seeds & Peanuts

How Long Do Hamsters Live

How long do hamsters live? This is one of the frequently asked questions by owners of hamsters. Hamsters are extremely social and inhabit large areas in nature,where they are active most of the day. They are good diggers. Most hamsters can live for several years,although the lifespan depends on the species.

Hamsters are rodents belonging to the cicada subfamily Cricetacea,which contains 21 species. They have become widely established as popular pets worldwide. The most familiar species of hamsters is the Syrian or golden hamster,which has been the most popular kind used as pets worldwide. Other species include black and red hamsters,hares and gerbils,hamsters with bellies,hamsters with elongated legs,and dwarf hamsters. The species are distributed worldwide in areas of Europe,Asia,North America,and Africa.

A hamsters lifespan depends on several factors. The age and health of the hamsters,their activity levels,the species of hamsters kept and other factors. The oldest hamsters belong to the species of cicada,which is believed to be an ancient specimen of its own species. Although some believe that this specie lived alongside modern hamsters in pre-historic times.

The lifespan of hamsters can range from a few months to a year and a half. Young hamsters live for a shorter duration because they are growing. Nevertheless,it is possible for them to live for several years. They reach maturity at about three years.

Wedged deep within the brain, two little wing-shaped nuggets of neurons called the suprachiasmatic nucleus serve as a master clock, setting the daily schedule for the entire body. The clock is like an orchestra conductor, says neurobiologist Samer Hattar of Johns Hopkins University. When the conductor tells the orchestra when to play, the music sounds really good, he says. But without a conductor to direct the timing, an orchestra can lose its rhythm.

Researchers have known for years that people who lose their daily rhythms through shift work or travel across time zones can suffer from memory problems. And recently, scientists have linked memory problems in the elderly to out-of-whack clocks. But why wonky schedules trigger these troubles is unclear, Hattar says.

Studies in animals have been confusing: Removing mices master clocks, for instance, disturbs daily rhythms but the animals memories remain intact. So Norman Ruby, a behavioral neuroscientist at Stanford University, and colleagues decided to study Siberian hamsters instead.

Hamsters gave the team more options: Researchers could either cut out the clock completely or leave it there and break it. Just a few well-timed pulses of light at night can confuse the animals clocks forever.

Coats The Different Types Of Syrian Hamster Coat

The first hamsters discovered had short hair, since thenn fancy breeders have managed to breed four different coated types. Shorthaired, Longhaired, Satin and Rex.

Long Haired Commonly referred to as Teddy Bear or Angora Hamsters have longer fur than usual. Only male hamsters can develop a long coat, often reaching the length of 3 or 4 inches. Male long haired Syrians have a skirt effect around their bottom section whereas females just have a fluffy all over look.

Long Haired Hamsters need attention when kept as pets because their fur becomes matted and tangled up easily as well as attracting individual substrates to sticking. Hamster owners can give their long coats a gentle grooming with a toothbrush or a small flea comb.

Satin Satin Syrians are beautiful animals with a glossy sheen to their coats. Some of the fur shafts are hollowed out which gives an ultra-shiny look. Breeding two Satin hamsters together is not recommended as the results are not favorable creating offspring with greasy, thin fur.

Rex Relatively new to North America Rex Syrians have been common in Europe for many years. Their biggest characteristic is their curly, crimped wavy coat. Their coats are typically very short and dense.

Hamster Fur Or Skin Problems

Some new owners find that after a few weeks the skin can be seen in areas because the fur has thinned or fallen out. This could be due to a small fight between two hamsters, some type of illness or continuous rubbing on the side of the cage, usually near the feeder. Note: you should only keep dwarf species in communities and not the larger golden breeds since they will fight.

Aside from a fight, the loss of fur can be caused by several conditions. One of these is due to molting. This is a normal process during the summer months where fur loss can be observed. Fur loss is also common in older hamsters. It starts around the abdomen and then spreads to the chest and limbs. This too is not anything to be overly concerned about. You may just need to change the diet up since vitamin deficiencies can also be the cause of the loss or thinning fur.

At the first sign of fur-loss consider the cause to be a vitamin deficiency. Try and rectify the problem by adding water-soluble vitamins to your hamsters diet to help restore any vitamin imbalance. Pet stores should have these water-soluble vitamins. A good way to take care of your pet is to also give it breakfast cereal or fresh vegetables from time to time.

Do Hamsters Recognize Their Owners

A hamster can get to know his or her owner over time and given enough bonding time. See, with the right amount of socialization, your hamster will begin to recognize you. In fact, after a while, theyll even start to bond you. However, hamsters wont bond with everyone in your life they typically to one or two people.

Stress Neurocircuits: Neuroendocrine Regulation

Hamstercitos :3: Los Tumores en los Hamters

In addition to activation of the PVN, SUB males possessed a selective increase in c-fos labeling in brain regions previously implicated in stress regulation: Cg cortex, lateral septum, BNST, MPOA, CeA, hypothalamus , and LC. This is one of the first studies to demonstrate that social stress activates neurons within distinct neurocircuits throughout the brain . The resultant pattern of neuronal activity parallels, in large part, the induction of immediate early genes after a variety of acute, nonsocial stressors .

The role of these various brain regions in regulation of the HPA axis has been the focus of several recent reviews and will be discussed here only briefly in light of our current findings. The activation of neurons within the CeA, anterior BNST, anterior MPOA, LS, DR, and LC is consistent with numerous studies showing that stimulation of these brain regions can increase levels of plasma glucocorticoids or adrenocorticotropin hormone , which is released from corticotropes in the anterior pituitary, leading to the synthesis and release of adrenal steroids . The role of several of these brain regions in facilitating adrenocortical activity is further supported by lesion studies showing that damage to cells within several of these areas can block or reduce glucocorticoid secretion in response to stress .

Larger than Dwarf Hamsters, The Syrian hamster also known as the Golden or Teddy bear hamster is a small rodent belonging to the Cricetinae family. Syrian hamsters have rapidly become very popular household pets in the western world ever since Professor Aharoni captured a female hamster and her 12 pubs in Aleppo Syria back in 1930.Indeed All Syrian hamsters that are available as pets can trace their ancestry back to this captured female. The Louisiana Veterinary Medical Association has stated that Syrian hamsters were introduced to North America in 1936 and were some of the first domesticated pet hamsters.

As their name suggests, these critters are native to Syria and parts of Israel however, Syrian hamsters have been found in other regions of the Middle East.

  • How Long Is A Hamsters Memory

    why you SHOULDN’T get a hamster

    Hamsters have fairly good spatial memories and can remember changes in daylight for several weeks. Anecdotal evidence indicates that hamsters can remember familiar humans for months or even years.

    Although it is difficult to quantify exactly how long hamsters can store memories, research indicates that spatial memory is an important part of their food foraging. When placed in a maze, they remember which branches had food and tend to explore those first even after several weeks. Hamsters use changes in the length of days to cue breeding, and researchers discovered that they can remember daylight changes for two to three weeks. Sudden disruptions of their circadian rhythms by changing light patterns affect their memories.
