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.
Super rats wear capes.
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.

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.

Before breeding rats, ensure that the rats you are breeding have good health histories and temperaments. Also remember that rats can produce up to 15 babies in just one litter, so be prepared to keep all of the babies that you can't find homes for. If you're sure you wish to breed your rats, introduce them to each other on neutral ground (for example a bathtub) to ensure they will not fight, then put them in the same (clean) cage together overnight. Female rats' pregnancy lasts for approximately 21 days, and you may not see any signs of pregnancy until late on in that period. However, look out for increase in weight (buying a set of scales in recommended), bulging stomach, increased appetite and nesting. Good luck breeding your rats.
You could try bringing in cats to control them, but then you would have cats eating anything palatable once the rats were gone. Or you could perform tubal ligation and vasectomies on enough rats to reduce their breeding rate. Or pay any inhabitants a small bounty for each adult rat, 3 times as much for each pregnant one, making sure that no one is breeding them just for the bounty.

Importing them is illegal, but not keeping them as pets or breeding them as such. The ban on keeping them as pets was lifted in 2008.
