Norway Rat


Raising Feeder Norway Rats: 
Information about Breeding, Food and Housing

For the Norway Rat


Unfortunately, Metal Monkey Exotics no longer keeps or breeds Norway rats!

In these pages I hope you will find some useful information to help you raise rats as feeders. I currently take care of Domestic Norway rats, but have in the past taken care of African Soft Fur rats (sorry no mice). If your just starting out, or have been doing this for years, I hope you can take something away from these pages and put it towards having a successful colony for years to come.

If you find anything out of the ordinary or something that you know is completely false, please send me an email or comment, and I will do my best to fix the error as soon as possible.

If you have any questions you think I may be able to answer, (or you’d rather that I venture out and find the answer), go ahead and email. 

We’ve put a lot of work into each piece, and want to remind everyone that if you like what we do here, please make a link back to this page, rather than infringing on copyrights.

We wouldn’t steal your works, please don’t take ours. Thanks for understanding!

  1. lots of info, thats great! I started breeding rats for feeders now iam trying to start a rattery, so the info is really helpful, but have you ever tryd cross breeding your rats?

    1. Hi Jamie:

      Thank you for the great comment, I try to work hard on this website to help out others. 🙂

      I am not sure what you mean as in cross breeding. Do you mean have I tried to cross breed an ASF and Norway rat? The answer to that is a resounding NO. I do not mix species, Norway rats hunt mice in the wild, an ASF looks closer to a large mouse than it does a Norway rat.

      As for breeding, they are considered to be from two different genus, one is Mastomys (or Praomys depending on the text) and the other is rattus. It would be a far fetched idea that the two species can successfully interbreed.

      As for cross breeding lines? Yes, I work with several different Norway rat and ASF lines, but I am very choosy about where I get any new bloodlines. I have a full running rattery and I can’t risk any illness or pest. I am a firm believer in tight lock down and quarantine over here.

      Thanks for the comments, hope to see you again.

  2. Its not as far fetched as you think it is? we only think these are more related to mice but in truth the chromosone count is closer to the rat than the mouse. Norway rat has 42 and asf has 50 and the mouse has 20, there is only a couple rule that are used to suggest that hybrid breeding is not possible one is that the animal must have features in common. Humans and ratttus rattus share the same chromosones 46 but do not share any of the same traits. There are other things that play a factor in this not being possible.
