? about breeding rats

[satomi325]

other then water and food what else can i throw in there tanks ?

Since you're using tanks, you can throw in hides and a wheel if you want. They like to chew things, so a cardboard box will suffice as a hide. Could even throw in some wood or sticks for them to chew up.

and how many females can i house together

As many as you want as long as they are in a reasonable sized space.
Usually people do 4-5 rats in those cement mixing tubs for the rodent racks. So you can probably house a ton of rats in a 40 gal.

and how deep should i put the bedding

Enough to cover the bottom of the cage. Maybe around an 3/4-1 inch.

also is it smart to line underneith the bedding maybe newspaper or will they tear it up ?

They'll probably tear it up and use it as nesting material.

how long to the babys stay with mom

Until they're weaned and eating solid food (around 4 weeks, give or take)

and is it safe to keep babys from a different mom in with another female ?

thanks

Yes, in general. Usually if you have multiple females together, they'll take turns caring for the babies.
