No. It is not legal nor physically possible.
Rats mate all year around. They might even have 100 babies in their lifetime!
To mate most likely.
Theoretically they could mate, but any resulting zygote wouldn't be likely to live very long. The genes for different bodily systems are probably not on the same chromosome in both rats and humans, so the resulting collection of genes wouldn't have enough genetic data (or the right combination of genetic data) to make up a functioning animal.
I think there are more rats in the world than humans.
They eat rats,humans,and Spiders
the rats eat meat as humans do
They atleast have 1 per mate with the father but they mate their own siblings
They dont. Any interraction is purely coincidental. Rats hate humans. They only like rats. Get some real friends man....
the fleas where the start whom travelled from china, they had a bacteria in them which the fleas where immune to this bacteria was called versinnia. when the fleas bit the rats (black rat's ) drink the blood they would vomit out that bacteria that the rat wasn't immune to... soon the rat would die. after the fleas wiped out all the black rats they had no food so they moved onto the the humans and animals! so technically it wasn't the fleas who caused the plague it was the bacteria versinnia
Yes, rats are almost everywhere that humans have went to.
they mate like any other mammal
I don't believe they can, because if rats from the same family mate, it can cause problem with the young babies, chances are they might not survive or have severe problems
