And to arrive at a more valid conclusion on what’s the appropriate number of rats to raise at a time, let’s first look at some of the key facts about rats as an animal(rodent).

Rat Farming

Rat Size

Rats, as recorded by the Integrated Taxonomic Information System (ITIS), are more than 60 species in number, which invariably implies that you can find them in almost all shapes and sizes. However, according to Encyclopedia Britannica, they are often 5 inches (12 centimeters), or longer.

Largest Species of Rat

The biggest species is the Bosavi woolly rat, which was discovered in 2009 in the rainforest of Papua New Guinea (and doesn’t have a scientific name yet). According to CNN, in terms of size, this rat measures proportionately to the size of a cat, at about 32.2 inches (82 cm) from nose to tail.  And surprisingly, it weighs about 3.3 lbs. The smallest, on the other hand, is the One of Osgood’s Vietnamese rat, which is often 5 to 7 inches long.

Rat Gender and Classification

As recorded by the Australian Broadcasting Corp., male rats are known as bucks, while female ones are known as does. The babies are known as pups or kittens, and a group of rats is known as mischief.

Rats Habitat

Unlike most animals, you can find a rat anywhere round the world. As stated by the Animal Diversity Web at the University of Michigan, you can always find rats like the rice-field ones in Southeast Asia; the Australian swamp rat is in Eastern Australia, the Norway or brown rats in every continent of the world except Antarctica, and so on.

Rat Behavior / Habits

While a good number of rats are nocturnal (see mainly at night), others such as brown or Norway rats are always awake day and night. Generally, rats live to forage and mate.

And unless a rat is trained and domesticated, they are often afraid of the sight of humans, and will quickly vanish when someone sees them. Also, they love walking n groups, with a male leader often leading the way. This habit is most commonly found in brown rats.

Understanding Rat Behavior

Rats Diet

Rats are omnivores, but many prefer meat when they can get it. House and brown rats usually use humans for their primary food source. They will scavenge through trash or eat any food that is left unprotected.

As recorded by Encyclopedia Britannica, rats have also been known to eat grain or kill insects, water creatures such as snails, fish, and mussels, small birds, mammals, and reptiles for food. Other rats, such as the Sulawesi white-tailed rat and Hoffman’s rat, prefer vegetarian fares such as seed and fruits.

So, now that we’ve known some facts about rats, it’s time to go back to our big question for the day; how many rats can you keep together?

How Many Rats Can You keep Together?

Given that rats are naturally scavengers, even when trained and domesticated, it is recommended for you to house at least two compatible rats together. However, if you wish to increase the number, you can do so by keeping them in compatible groups because companionship is a vital aspect of rat’s scare. Put differently; they thrive well when they have another rat around.

And in other to prevent an infestation of rats in your home as a result of the groupings, you’ll have to be extremely careful not to group male and female rats in one cage, as that would cause them to mate and give birth to new baby rats.

Also, you will need to be careful not to mix the entire male rats with an entire female rats, to avoid having any unintended litters of baby rats.

Another thing you might want to look out for is in grouping all males together, as that could cause them to fight and make noise all over your house every single moment. If you must keep all the males in one place or while mixing, you should do so when they are young, so they can grow and learn to tolerate each other. Below are some of the things you should keep in mind when building or getting a cage to group your rats.
