Adopting from a Animal shelter.?

There are four brother rats at an Animal Rescue League. They are five weeks old and are weaned from their mother. I want to adopt only two, is that right to separate them?
yes. it will be fine.
at any pet store, there is an entire load, and they are separated all the time. especially if you pilfer two, because they will each still have one of their siblings with them. and after time go by, they wont even remember their old family so it wont matter. :)
Yes, they will do fine. It isn't approaching separating human babies from their moms. I had a rabbit who had eight babies this past summer. Believe me, I couldn't hang on to eight rabbits. Once they were old enough I found them homes. I hold the mom and dad and they were fine. She didn't even seem to miss them.
Yes, because they might miss respectively other but as long as they still have some other rat that keeps the company it will be ok.
They are similar to any other animal and will do fine being separated. Don't worry about it. If they realize it, it is one and only for a short while. Having two of them, they will still have a playmate and companion, so they will do great. Don't worry about it.
Answers:    Yes, it's fine.

Rats do best when kept in same-sex pairs.

They do savour the company of other rats, so keeping 2 together makes sense. You don't want to mix the sexes unless you want LOTS of baby rats!

A pet rat kept alone is not the best idea ... it become territorial and anti-social, and potentially aggressive.

Adopting two of the same sex is absolutely the right thing to do.
make certain that they are old enough to take solid food, save for that, they should be fine :)
