You can put a male and female rat together if you want them to mate and have babies. You could breed any size of rats.
No. The average lifespan of a wild rat is a bit less than a year. Assuming a couple begins breeding as soon as they are mature, and continue breeding, the couple would have 54 little rats in one year. If THEIR babies begin breeding as soon as mature, and the grandbaby rats did likewise, there would be a total of 1,808 rats after 1 year- assuming none died during the year. Fifteen thousand is not a realistic number.
You should place the rat traps in obscure places. Places that are hard to reach for human beings but easy for the rats. This is where the rats will be at. Cheese and peanut butter are good baits to lose.

Good breeding places~ At home, vet, friend's house (a friend that doesn't have a dog but have experienced having a dog will be best) Bad breeding places~ At the street, unhygienic places.
A cathouse, good sir.

Stagnant water.
yes because rats can't fit in most of the places mice fit in.
Most rats generally eat about 30 grams a day in food, but this can vary depending on a rats age, size, weight, if it's breeding or not & what season it is.
no they can't, they even live in dark places
