Yes
It might depend on what type of rat it is or where did came from or is it vicious.
the adult might eat the baby :/
Just use a large bird cage, or a rabbit cage. My rat has a rabbit cage, and she's as happy as can be. My old rat had a bird cage, and he was perfectly fine.
since no one has answered you... I thought I would let you know my rat killed and ate my two gerbils. I let her out for a while and she found a way into the gerbil cage and she attacked them. ick. Another rat I had killed it's cage mate (rat).
Only if the rat is smaller than the ferret or close to the same size.
If your rat is freaking out, introduce a same sex cage mate because rats are highly social animals.
no.

You should not keep a rat and a mouse on the same cage together, The rat will most likely kill the mouse as that is their natural instinct.
No. Hamster rat cage don't have enough space to pet rats. You can use Midwest Critter Nation rat cage. It has plenty of space to play and move around. You can check the reviews here- bestratpoisons. com/rat-cage-for-2-rats
The rat will more than likely kill and eat it. Rats are predatory species, and will prey on smaller rodents.
Some can coexist in the same cage. When rooming together keep watch for the first day to stop any fighting problems.
