Well I have a one-room bedsit so I don't have a lot of choice really! They sleep with me   I have got used to the noise, but it drove my poor Mum mad when she came to stay. In the end I had to put them in the kitchen.

My Romeo, male, is in my bedroom.  He is still in quarantine, plus he is being treated for mites! My girls were in our dining room until I got a crazy rat hungry foster dog!  I foster for a rescue. I feared for my rats, so they are in our downstairs living room safe from the dog.  I think my other dogs miss them though!

Ours are in the bedroom (the only room where we can shut the cats out easily when necessary).

When they were babies it was an absolute nightmare, we had many sleepless nights! They've definitely chilled out now though (or have we just got used to it?!) and we don't hear them much at all.

Our girls big cage is in the living room.  Mr. Higgins has a smaller cage that goes into my daughter's bedroom at night and comes down into the living room or dining room during the day

All my boys are in the bedroom!  It's hard to sleep at first, but after a while you get used to it!  

Our 5 boys are in a 4-foot-tall ferret cage right in the corner of the living room, and our hedgehog has her cage in another corner across from the ratties.  We like having our furbabies right there with the rest of the family, particularly in the evenings, when the ratties and hedgie are up and feeling like playing and cuddling.  

Honestly, the living room is about the only area where there is enough room for the cages anyway, but I'm not sure I'd want our nocturnal critters in the bedroom. We have enough trouble with our 3 cats and our dog keeping us up at night as it is!  

I'm temporarily living in a teeny one bedroom apartment, an the best place for my rats ended up being next to the dining room table, not only because of the space, but the tile floor .  It makes dinner time interesting, trying not to give in to their oh so cute faces begging for food!

They are also by a window so on warm days I open the bilnds for them and crack open the window....in fact, I'll go do that right now.....

The girls live in our living room where we can see em...better than the telly these days lol ..god I sound old!!
I let them out for a long old play in the evening but more n more the cage is left open as I found the rat asleep on the dog!!!lol  None of the animals in my house seem at all interseted in the gals so although I am careful more n more they have a free wander!!
Jules n the gals

the rattie girls cage is in the kitchen/den combo room.   Which is also where the computer is.  I love watching listening to them move around and play.  They also get out time on the kitchen island.  

my rats are in the finished part of the basement.  the reason being, this is the toy room, and computer and game room, and also it remains constant temperature year round, so I can modify the humidity/heating for my reptiles as well far easier than the other rooms in the house..  

Mine are usually in the living room where they get lots of attention, but we recently got a new dog that hasn't figured out yet that the rats are not dog treats.  So for now they live in the guest room with the door closed.  But they live in a Martins R-695 that stays open all the time on top of a 4' long table, so they are very happy!    I did have to put a sheet on the wall though since they decided they didn't like the color of the paint.

Ours are in the Living room atop our (used to be) kitchen table.  Now we eat off of T.V. trays!      Just finished setting up a little "rattie gymnasium" using their cages, a Glad box, an old pair of flannel PJ bottoms, and a Wobust Wodent Wheel!  The girls enjoy climbing around in it, as well as on it, but Ayo is not too impressed with my handiwork.    ah, well.

Mine are in the living room.  I have a little cage on the side table right next to my recliner that my girl Sara is in.  I sit in the recliner and she sits in her hammock.  When I call her, she comes running to the side of the cage where I am.  

Then I have my big Fatso male in an aquarium on the floor but when I'm home, I take him out and put him on top where he just sits and watches the crazy house hold here (two dogs and the parrot).

i keep my 2 rats in my bedroom. when i first got rocky he was very noisey.. especially at night. then i got him a mate Pebblez and now they make more noise. but i live with cats so i have to keep them in my room so the cats wont knock over their cage. the only down side to havin rats in my room is that when the cage needs to be clean my whole room gets the smell.. eww.. but i have been keeping them very clean so everythings working out fine

i keep my rats in my bed roon too aswell as my Hamster and Fish. but they don't keep me up at night.

The 7 that live  at home live in the computer room.  Their play area is the laundry room during the cold months and the garage when it warms up.

My school rats inhabit the entire counter space that runs across the back of my room.   In the summer, they live in the garage.  I air condition it on really hot days by leaving open the door to the laundry room and running a fan.  Other days they get some fresh air, which they seem to love!

The garage set up consists of 3 cardtables with two 8 foot pieces of plywood stretched across them. A section of the area is for cages and the rest has tons of toys, boxes, tubes, digging boxes, etc. . .
