What rodents can be kept in male pairs?

I know that the two males would have to be from the same litter, but I've been getting mixed answers about details; which kinds of rodents can be kept in pairs (males)?What rodents can be kept in male pairs?
umm let me think, roborovski hamsters, rats, dwarf hamsters (sometimes), and regular hamsters (only if raised together or placed in same cage at petstore, must buy both at same time)What rodents can be kept in male pairs?
All male rodents should be able to be kept together with the exception of strictly solitary rodents like Syrian hamsters. The only way they can be kept together, though is if they are met when very young (same litter, as you said). Males, despite being in the same litter, may still fight. Usually it's just a little argument, but sometimes (like with mice) it could turn deadly. The best thing to do is to get females from the same litter. I prefer female rodents, anyways. They always smell better and don't have 'big butts' as I've said since I was little.
Two males don't necessarily have to be from the same litter. At least, not with rats. It's definitely easier if they are, because they already know each other, but many rats can be introduced later in life and get along fine, as long as you're careful.





Rats are a great pet, and the only rodent I know anything about. :) All rats need to be kept in groups of at least two, but the more the merrier.
Male rats can be kept together, and don't have to be from the same litter. Even male rats that have never met before will usually get along fine. It's a common misconception that all male rodents fight; most will get along just fine as long as they don't have a female to fight over.
I am pretty sure any rodents can be kept in male pairs. They don't have to be from the same litter, but you might need to ease into the introduction process. You should check the websites I list, they are specifically for rats (which I have and LOVE, they are great pets) but I am pretty sure the tips they have are good ideas for any rodents.





(If you get two rodents at the same time where they have been kept in the same cage at a pet store or whatever, they will probably be fine from the start.)
Gerbils, Guinea Pigs, Rats, mice.





NOT: HAMSTERS!





I prefer gerbils, they are small, fun to watch, super friendly. They are the least smelly of all rodents. The live long lives for being a pocket pet. They are low maintenance and don't have any special dietary needs. They don't take up a lot of space. They sleep at night, and they hardly ever bite. If you get them from a breeder, they are already ';jump in your hand friendly.';

my male rats get along together splendidly. from experience, i'd say do NOT put together male hamsters or mice. i've had plenty of problems with them fighting which ended up in vet visits and have to figure out multiple living situations.
All rodents can be kept in male pairs, they wont fight unless there is a female around.
I know guinea pigs can.... other then that, my knowledge ends. Sorry.





Edit:: I'm so stupid, I forgot about rats! Rats and guinea pigs are similar in the sense that they need companions.
guinea pigs, But and it doesn't have to be from the same litter they could have like grown up together in the same cage.. or known each other for like long time..
just about all male pair rodents will fight, but personaly i would say get a pair of rats, well as long as they have been together when you buy them it should be fine, but they might fight some time!!
