how long can a rat swim
QUESTION: How long can a rat swim? Survey saysâ¦ 15 minutes. For 15 minutes, a rat tossed into a bucket of water will kick its little rat legs, paddle like a dog, and fight to keep its head above water. So what happens after 15 minutes? The rat sinks like a little rat rock. So you might conclude from this data that a ratâs physiology can only withstand 15 minutes of swimming before it ultimately succumbs to a watery grave. But where this little tale gets interesting has nothing to do with rat physiology, but rather rat psychology.
