WOW! 16 any genetic?

lol.. well at the moment I'm trying to feed 20 snakes.

I'm sure any pet store albino rat will do a fine job for you.

how much did you pay for her?

I got her for free.. my cousin gave her to me.

Pet store rats usually are anywhere from $5-10.

what size would you suggest to get?( i need it to breed right away) small medium large or jumbo?

Large.

I have a male and a female right now but the thing is is I had her for around 3-4 weeks and the day I got them mated and they where in the same cage before. I wonder she didnt have any babies. they are really old as i got them from ym moms friend and she told me they where old but still reproduced. do you think she cant have any more babies or the male isnt viable any more?

I don't know, but older rats sometimes don't have a litter every month, but every couple of months.

I'd get a new male and female. You might want to get the male from a different shop from the female to make sure they aren't littermates.

whats wrong with them being litter mates?

Inbreeding!

You'll likely get deformed, weak babies.. not good.

what about if I trade them in and get them from one petstore and ask if they are litter mates?
