How Long Do Rats Live As Pets

Life spans for rats are variable and pet shops will advertise different lifespans. In the UK, a normal rat’s lifespan is two to three years. Rats have a longer lifespan, ranging from three to five years. Genetics and environment are also factors. A rat that is properly cared for and fed can live a long, healthy life. How Long Do Rats Live As Pets?

The life expectancy of a pet rat


Rats have long lives, but their life spans are often limited by certain conditions. One of the most common conditions is chronic stress, which can have negative health effects. Chronic stress is often caused by changes in routine and environment. For example, rats who have been exposed to frequent moving or a new cage will have less energy and may begin to develop symptoms similar to depression and PTSD. Other conditions that can cause chronic stress in rats include illness, overcrowding, the death of a cage mate, and social stress.

 The lifespan of pet rats is largely determined by the care the rat is provided with. Some people report that rats can live up to three years with the right care. However, it is important to keep in mind that this isn’t the norm. Most pets won’t live that long no matter how well they are taken care of. A life expectancy of two to three years is listed by Wikipedia. While Angela’s survey was informal, a more formal study of rat life expectancy has been undertaken by UK breeder Mary Giles.

Factors that affect lifespan


Rats can live for a long time, but the length of life depends on several factors. First, the genetics of your pet’s parents play an important role. Rats born with recessive genes are more susceptible to illnesses and diseases than other animals. For this reason, it’s important to find a good breeder for your pet. Not only does it assure you of getting a healthy rat, but it also has a variety of benefits for you. For example, a good breeder will have handled babies from birth and provided an active and stimulating environment.

 Rats need social interaction. When they are isolated, they undergo chronic stress, which can shorten their lives. By providing them with social enrichment, you can help them extend their lives. Some researchers have found that positive noise stimulation, such as classical music played at higher pitches, reduces stress in rats. Keeping rats in a safe environment with a consistent routine can significantly extend their lifespan.



Rats can be bred to look different in different ways. Some rats are albino, which masks the natural color of their fur and eyes. Others have merle-colored fur, and some are tailless. These types are different from one another in that their tails can be stumpy or even absent. While taillessness is an extremely uncommon trait in rats, it can also lead to severe birth defects. The differences between types are largely determined by the specific mutations within the rat’s genetics.Rats have a total of 25,000 genes, which tell the cells in their bodies what to do. These genes are found on chromosomes, which are strands of DNA inside the nucleus of each cell. Rats inherit one chromosome from their mother and one from their father. Their chromosomes have two copies of each gene. Each copy is called an allele.



One of the most important considerations in caring for rats as pets are the environment. Rats prefer an environment where the temperature ranges from 72 to 80 degrees. High temperatures or low temperatures can stress them. However, there are certain guidelines for the temperature ranges to be kept in mind to ensure optimal conditions. For instance, rats that live in a laboratory environment have a preferred temperature range of 20 to 26 degrees Celsius or 68 to 78.8 degrees Fahrenheit. In addition, rats can be kept in a small aquarium, which tends to be less drafty and smaller than a cage. The aquariums can also be used to house hairless rats, new litter, and ill rats.

 Rats as pets also raise questions related to the relationship between pet rats and rodent-borne diseases, such as the prevention of disease in wild rats. Public health authorities have attempted to communicate information about this relationship in the context of the Seoul hantavirus outbreak, but this has had limited success. Therefore, researchers conducted semi-structured interviews with people who keep rats as pets. The interviews lasted for forty to ninety minutes and were transcribed verbatim.



Rats’ lifespans depend on several factors, including the conditions they’re raised in, the type of diet they eat, and their genetics. Generally, rats can live up to three years. However, some factors may make rats more likely to die young, including lack of exercise and obesity.

 New rats can be introduced to each other in the same cage after they’re about 12 weeks old. However, this process can be a little bit difficult for older rats and for animals that have always lived alone. While many rats are accepting of a new companion, some will not take to the new environment. In these cases, it may be necessary to separate the rats after a few days to avoid problems down the road.

Rats spend two-thirds of their day sleeping, while the remainder of their day is spent awake. To ensure they get a good night’s rest, make sure their cage is dark and noise-free. Rats need to interact with other rats, as loneliness can cause unwanted stress.
