Rat – Standard

Growth Size

Rats grow to a length of 15 – 20cm (not including the tail), and a weight of 200 – 500g.


2 – 3 years.


Contrary to popular belief, rats make affectionate and loving pets. They form bonds with their owners and may even 'purr' in delight when being scratched in the right spot!

Training Difficulty

Rats are incredibly intelligent and can be trained to do a number of tasks. Most commonly they are trained to complete mazes as part of scientific studies. At home though, they can easily be trained to use a litter tray, among other things. Rats are treat motivated, so food is the key to getting them to learn new tricks.

Recommended Owners

Rats are a great pet for responsible children over the age of 10. Younger kids may be too rough and unintentionally hurt the rat, or get bitten.


In the 18th and 19th centuries, rats were originally used in bloodsports. Sportsmen would fill a pit with several Rats and place bets on how long it took for a terrier to kill them all. However, as the sport continued, different and unusually coloured Rats emerged. These were soon tamed, selectively bred, and sold as pets.


Many different types of fresh fruit and vegetables can be fed to Rats. These can include: apple, banana, beans, melon, stone and citrus fruit, broccoli, carrot, Asian greens, celery, tomato, and peas. In addition, commercial Rat or Mouse pellets can be fed.

Please note! The dietary guidelines specified above are only a guide and feeding may vary based on your pet's size, activity level, and metabolism.


Rats are very clean animals, and are happy to self-groom. They may need their nails trimmed occasionally.


Oils in cedar and pine wood shavings are toxic to Rats. It it much better to use shredded paper or hardwood shavings as bedding.
