How Big Rats Get

If you’re wondering how big rats get, you’re not alone. Rats are becoming larger all the time, and their physical size is improving, thanks to better food. This, in turn, means that they’re living longer and healthier lives. But what are the reasons for these increased sizes? Here are some of the possible answers.

Rats can reach 18 inches long, including their tail. They can also survive three days in water. In the wild, rat size varies widely. Some can be as big as two pounds, while others grow to be smaller. The size of adult rats depends on how much food they eat. And their teeth never stop growing, so you never know which one might be the biggest!

In 2009, biologists from the Smithsonian Institution discovered a new species of giant rat. They called it the Bosavi woolly rat. This 3.5-pound rat was 32 inches long, and had a silver-gray coat. The researchers think it might live inside the Mount Bosavi volcano. The scientists also said that the rat was completely unafraid of humans. The researchers believe that giant rats have adapted to living in such remote environments.

The bushy-tailed woodrat’s range is quite large. They can grow to be between 300 and 600 grams and average at 405 grams. Females, meanwhile, are slightly smaller, weighing about 270-320 grams.
