Look at the size of the most obvious is the body type, but half a year of hamsters and a year of the kind is basically indistinguishable, born 1-2 months of body size is smaller, and then slowly will grow up, to a certain extent after not long.

1.Hamsters can grow up to 11-15 cm and weigh between 30-40g when they reach adulthood, making them very small rodents. Now the more common pet hamsters are chipmunks, husbands, old women, three-line hamsters, silver foxes, golden bears, etc.

Hamsters are solitary pets, and if multiple are kept together, there will be fights or indiscriminate breeding. When it is serious, the strong will eat the weak.

2.Hamsters are small breeds, there are many varieties of hamsters, generally will grow to about 8-12 cm, the weight will be maintained at about 30 to 40 grams, a large range and the basic standard is like this, there are more than the front belt, mainly depends on how it is usually fed, but also depends on the usual amount of exercise of hamsters, the life span of hamsters is generally one and a half to three years.

3.Under normal circumstances, hamsters will grow to about 8-12cm and weigh about 30-40g. How big a hamster can grow is mainly related to the breed, for example, ** rats will generally grow to 12-20cm, Gakaria hamsters will generally grow to 7-12cm, Canberle hamsters will generally grow to 7-12cm, and Robrovsky hamsters will generally grow to 4-5cm.

In addition to the breed, the size of the hamster is also inseparable from the owner's feeding method, and the hamster's feeding method is as follows:

1. Hamsters mainly eat reed rat food, and can also feed some peanuts, melon seeds, walnuts, vegetable leaves, carrots, apples and other foods in moderation.

2. Environment: To provide a comfortable and hygienic environment for hamsters, a comfortable and hygienic environment can make them healthier, and healthy hamsters will naturally live longer.

3. Injury and illness: Injury or illness may reduce the life span of the hamster, so if the hamster is injured or sick, the owner should take medicine and seek medical attention in time**.

First of all, how big a hamster can grow is inseparable from its breed, and it is also related to the pet owner's feeding method. For example, a more common hamster on the market, the silver fox hamster, has been raised by many people in recent years because of its good-looking appearance. How big a silver fox hamster can grow is influenced by genes, which determine their smaller size.

Even after adulthood, silver fox hamsters are not very large. Normally, the silver fox hamster is about 8 to 11 centimeters long and weighs about 30 to 45 grams when it reaches adulthood, making it a smaller hamster.

The lifespan of hamsters is generally between 2 and 3 years. In fact, many hamsters begin to senescence after 1 year of age, and at 2 years of age, they will appear to be visibly old. For example, the coat color is not as shiny as before, the coat falls off, the blind waiter ** is flabby, and the movement is slow.

So at this time, pet owners need to treat them well.

Generally, hamsters don't grow big.

To determine the age of hamsters, you can observe their hair, eyes, ears, appearance and lactation, and the newly born hamsters** are pink, with only short thin hairs, and their eyes and ears are tightly closed. Within half a month, the ears will open, and the eyes will also open, and the hamster at about 3 weeks is the epitome of the parents, and the hamster under the age of one month needs to be breastfed.

First of all, you can observe the hair of the hamster, the newborn hamster** is pink, and the whole body is covered with fine short fluff. As you grow older, your hair becomes longer and darker, and as you get older, your hair becomes sparse and dry.

Secondly, you can observe the ears and eyes of the hamster, the ears of the newborn young rats are tightly closed, and the eyes cannot be opened. 1 Within 2 weeks, the ears of the young mice will open, and after half a month, the eyes will slowly open.

The age can also be judged according to their appearance and lactation, and the baby hamster at about 3 weeks is a smaller version of the parent. Hamsters are most likely weaned at 3 to 4 weeks, and if they need to be breastfed, they are not yet full of months.

1. Juvenile mice: weaned to 3 months old, relatively small, the hair on the body is fetal hair, fine and soft to the touch, that is, young hamsters;

2. Adult nuclear mice: 3 months old to before the age of the mouse, the body size is larger than that of the young mouse, and the hair on the body becomes thicker, that is, the adult mouse;

3. Elderly rats change macro after the age of the year, the body size is larger than the young rats, the hamsters over 2 years old are thin, the coat color becomes dull, there is a phenomenon of hair loss, and even a large amount of hair removal is extinct, and they do not like to move, that is, they are elderly mice.

The age of a hamster can usually be judged from several aspects:

Instructions at the time of purchase: If the hamster is purchased from a pet store or breeder, there will usually be a record of the date or month of birth.

Hair color and condition: The color and state of a hamster's coat can also indicate its age, and in general, older hamsters will have dull or somewhat depigmented hair.

Body size and weight: Hamsters grow rapidly within a few months of birth, so the size and weight of a hamster is also a way to tell how old it is.

Dental condition: Hamsters' teeth wear out and turn yellow with age, so the approximate age of a hamster can be judged by examining the state of its teeth.
