WOW! 16 any genetic?

They most likely won't know.. they may even tell you they aren't if they think it'll make you buy two.

I'd play it safe and buy from different sources.

okay i am going to buy a female from pet co and then another one from a mom and pop store. is that okay?

That should be good :) It is always good to keep fresh blood coming into any breeding project.

do you think the males is okay and just buy 2 females instead buying another male?

Males slow down too.. do it if you want to, but rats only live 2-3 years.. after they're a year old I usually 'recycle' them anyway.

I bet hes atleast 1 year old. Im going to freeze them both. what is the best way to kill them? I do not have a co2 chamber.

Hm.. C02 really is the best.

You have a strong arm? You really have to slam them hard if you want to use the whack method. (it is a rat right? can't see if you have been talking about your mice or rat pair.. lol) Mice are easy to kill by whack method, though they do twitch like mad for a little while.

Try putting the rat in a pillow case and whack it against something very hard.

I don't know about other methods..

they are rats. I have a strong arm. the rats are pretty huge tho.

Yeah. They are not easy to whack.

Really you should consider setting up a Co2 chamber, especially if you're going to be killing a lot of rats.

how much does it cost?
