Rats

Do you know maybe if the name-Rattus norvegicus is the same for a wild rats and those who we keep at home?

[Solaris Shadow Paws]

no, it is not the same to my knowledge. Look at the wolf and the domesticated dog. Canis Lupus and Canis Lupus Familiaris.

It depends of what kinds of rats are you talking about. For example, lets say that the dog who is kept home as pet and the dog who is living in wildernes they are the same. They have the same genome and chromosome numbers so if you do DNA samples they match each other. there are 67 species in Genus Rattus in world. So if yu send a photo of those that you are mentioning here I can help you, even I have fobia from Rats.

Yes, Rattus norvegicus is oftenly made as a pet or as a scinetific subject. It has a wild population that exist normaly in many parts of the world nowday since it has been intorduced in many part via ships and transports. This is not the case like in domesticated wolf or dog. Though there is many need for breeding rats in captivity very abudant populations exist in wild. There is also Rattus rattus or black rat that also lives in many part of world where R. norvegicus live but this species is not so used as pets or science subject.

[Dr.Stein]

To identify until species level, we need a sample.

About dog and wolf mentioned above, if it is named that way, it means that they are one species but different subspecies. Subspecies can be generated from domestication. Another example: Gallus gallus varius (Wild chicken) and Gallus gallus domesticus (Domesticated chicken).

Thanks a lot for those great explanations!
What about the rats fobia, i see that i'm not the only one. In fact my knowlege about their species is not really wide but practical observation of behaviour is that what intrest me. maybe looking after such an animal in domestic enviroment is not the best way, thought it gives you a good knowlege of its inteligence.
