How Small Can Rats Squeeze Through a Hole?

Rats are tiny creatures, but they have the ability to squeeze through even the smallest of holes. The cylindrical shape of their body, as well as their stiff bones, enable them to squeeze through tiny spaces. They are burrowing animals and spend much of their life in small, tight spaces. In fact, they can squeeze through holes that are just one-third inch in diameter.

In order to fit into these tight spaces, rats have evolved special adaptations that enable them to squeeze through tiny holes. For example, they have eel-like whiskers on their heads that help them determine if the head of the hole will fit in it. If the head fits, the rest of the body will follow. But if the rat is overweight, its body may not be able to squeeze through the hole after the head. This may be due to the fact that the rat has limited grip and leverage and is unable to squeeze its entire body through the hole.

However, it’s still worth noting that a healthy adult rat can squeeze through a hole that is 0.705 inches in diameter. However, an overweight rat will not fit through a hole of this size.
