When you ask were there rats on the ship, the most careful answer is that no one has confirmed a shipboard rodent presence in the key outbreak story people are discussing. The public evidence points to a hantavirus case cluster tied to the MV Hondius. Investigators still have not pinned down the exact path of…
Rats can live in the walls, and the signs often appear before you ever see a rat. Scratching at night, scurrying behind drywall, droppings near hidden corners, and gnaw marks around weak spots all point to a hidden problem. If you catch the activity early, you can get rid of rats in walls more safely…
Rats are social, opportunistic animals, so the answer to is it normal for rats to eat each other is no, not in a healthy group. When you see it, stress, hunger, illness, crowding, or another serious problem is usually changing rat behavior in a dramatic way. Healthy rats do not normally cannibalize each other. Rats…
You may see pet rats interact, and that can look intense fast. Yes, rats normally play fight when the behavior stays bouncy, balanced, and brief, with no injuries or panic. Rats often play fight by wrestling, chasing, pinning, and quickly switching roles. Real trouble looks stiffer, one-sided, and more stressful, so the whole interaction matters…
If you are asking is it normal for rats to be out during the day, the short answer is no, not usually. Rats are mostly active at night, so daytime rat sightings often point to stress, food pressure, disturbance, or a larger rat problem nearby. The context matters, including what you see, where you see…
Rats did not originate in the Americas before Columbus, at least not the invasive rat species most people mean by “rat.” Old World rats arrived with European ships, while the Americas already had many native rodents and other small animals. The evidence shows that invasive black and brown rats were not present, though native rodent…
You may have heard the phrase were rats alive with dinosaurs, and the short answer is no, not the modern rats you know today. Dinosaurs vanished about 66 million years ago. True rats appeared much later in mammal evolution. Small mammals, including rat-like ancestors and other early mammals, lived alongside dinosaurs during the late Cretaceous….
Sneezing in rats can be harmless when it happens once in a while. Repeated sneezing can point to irritation, stress, or a respiratory problem. If you are asking, is it normal for rats to sneeze a lot, the short answer is that occasional rat sneezes can be normal. Frequent or worsening sneezing deserves a closer…
You might picture a modern brown rat darting under a dinosaur’s feet, but that image is not quite right. Modern rats did not live alongside dinosaurs, although some small mammal relatives did. That difference matters because “rat” can mean a very specific animal today. Your answer changes depending on whether you mean the modern genus…
It is natural to worry about rabies after a rat encounter, especially if you have a fresh bite or scratch. The good news is that rabies from rats is extraordinarily rare in the United States. The bigger short-term risk after a rat bite is usually bacterial infection rather than rabies. Rats are mammals, so the…
