Rats are an extremely popular pet to have. They are relatively low maintenance, and although it is quite sad that they only live to be around 3 years old this makes them perfect if you can’t commit to a long-term pet such as a dog or a cat which can live to be older than 15 years. But what is a good rat diet?
They are extremely easy to tame, they are sociable and are very friendly too. Despite their reputation, they are actually incredibly clean creatures. In fact, rats are cleaner than cats!
They are commonly white, black, and cinnamon and have red or black eyes. They are rather cute little creatures, and make lifelong bonds with their owners. They can recognise who their owners are, and will try to groom their humans as if they were a part of their rat pack. They are mostly active at night and are predominantly nocturnal creatures.
Males are bigger and lazier than females, and females can start going into heat at around 6 weeks old so they are easy to breed.
