Best rat cages

Finding the best rat cage for your rodent friends can be hard but it is also the most important task because the cage your rats are living in has a huge impact on the quality of their lives. They spend most of their life in a cage so having a good cage makes them happy and satisfied. Spending some extra time to find that perfect rat cage is definitely worth it!

There are many things to consider when purchasing the perfect habitat for your pets. Here’s a list of everything you should keep in mind while you’re on your quest. Plus, at the bottom of the post, you’ll find our list of the best rat cages.

How to choose the best rat cage for your pets?

So many rat cages the market, from small cages, large ones, metal, plastic, glass cages, 1, 2 or 3-story cages and so on. Which one would be the best choice for your rats? Make sure to keep an eye on the following things, while you’re looking for the perfect new cage for your rats.

Wire spacing on rat cages

How big should a rat cage be?

A general rule is that there should be at least 2 cubic feet per rat. Minimum size of the cage for 2 rats is 29” x 15” x 18” (72cm x 36cm x 44cm). You can try this rat cage size calculator to check if a cage would be big enough for your rats before you make a purchase.

There are some starter cages to buy which can make a good choice if you have baby rats. But one thing to keep in mind is that rats grow quite fast and will outgrow their small cage in 3-4 months. It would probably be the best to buy adult size rat cage right away and save the money.

Rats need plenty of room to roam, climb, and play so they would be unhappy living in a small cage. Bigger is always better!

Bar spacing

To prevent your rats from going out of the cage as they please, make sure the cage has small bar spacing:

  • 1/2″ or less for baby rats
  • maximum of 1″ for adult rats

If your adult rats are very small, it is best to get a cage with the bar spacing of 1/2″.

Many cages sold for small animals would not be able to hold rats because of their wide bars, so make sure to check the bar spacing before purchasing.

What should the rat cage be made of?

Rat cages with metal wires make the best choice as rats like to climb up the wires. Plus, those cages provide good ventilation and are easy to clean.

Metal cage is the best choice for keeping your rats happy and healthy, but not all metal cages are the same. Choose the cage with coated metal wires to prevent it from rusting.

Ease of cleaning

You’re going to spend a lot of time cleaning the mess your rodent friends did in the cage so for your convenience, a rat cage that is easy to clean is your best bet. Look for a cage with large doorways that make all parts of the cage easily accessible for cleaning. Removable flooring will also make it a lot easier to clean.

Avoid these types of cages

Cage made of wood

Wooden cages

Wooden cages are not a good option because wood soaks up rat’s urine so it starts to smell. Also, the wood is very hard to disinfect which makes wooden cages unhealthy for rats. If you do choose wooden cage after all, make sure to coat it with something to make it urine-resistant. Also, make sure to only use wood that is safe for the rats.

I often see pins of creative homemade wooden rat cages while browsing Pinterest. Those cages do look great but, unfortunately, they do not provide the best home for the rats. Resist those nice looking wooden cages and always opt for a metal one to be on the safe side.

Glass aquariums and plastic bins

Glass aquariums and plastic bins are not the best choice for keeping rats as they keep in dust and ammonia which irritates the rat’s respiratory system.

Cages with wire mesh flooring

Avoid cages with wire mesh flooring because they are not good for rats’ feet. Constantly walking on the wires can cause a condition called bumblefoot on your rats’ feet which manifests in swollen and infected feet. You wouldn’t want that for your rats!

Cages with wire mesh flooring are primarily made for the poop to slide through so that rats don’t have to walk on their feces. Although that sounds like a good idea, this type of cage is not healthy for the rats’ little feet. If you do get a rat cage with wire mesh flooring, you should cover it with something solid to prevent this from happening and just clean up the poop more often.

The best rat cages for adult rats

The following list contains the best rat cages we could find! These cages are spacious and have a lot of add-ons that’ll keep your rats entertained at all times.

Critter Nation 2-Story Small Animal Cage

Critter Nation 2-Story Rat Cage

Critter Nation 2-Story Cage – check current price on Amazon

This cage is my favorite and the one I would highly recommend. This 2 story rat cage has plenty of room for the rats to play in and rest. It is equipped with three ramps and ramp covers, two resting shelves that will keep your rat busy and entertained.

  • 1/2″ bar spacing makes it easy for rats to climb and explore without an escape option
  • Solid floor base won’t cause any issues for the rats’ feet
  • Can be easily transferred through the room with 4 locking wheel casters
  • Has a lot of room for the rats and can easily hold many cage accessories such as hammocks, toys and tubes – 36 x 25 x 62.5 inches

  • It can be hard to assemble

Ferret Nation Ferret Cage

This 2 story cage includes two pans, two shelves and three ramps. It also comes in a 1-story version but as I always say – the bigger the better. 1-inch bar spacing makes it suitable for adult rats.


  • Easy to clean because of the full-width double doors and removable shelves
  • Solid floor base
  • A lot of room to play: 36″L x 25″W x 62.5″H

  • Some people received bent metal parts so it was harder to assemble than expected

Prevue Hendryx Black Feisty Ferret Cage

Prevue Ferret Cage for rats

Prevue Hendryx Black Feisty Ferret Cage – check current price on Amazon

This one is a bit cheaper so it can be a good choice if money is an issue. It is spacious and includes 3 platforms, 3 ramps and 1 hammock for your rats to enjoy. The bar spacing is 7/8 inches (0.875 inches) which makes it suitable for adults rats but not for babies as they might get away. But this cage has one con to take into consideration, see below.


  • Plenty of room to run around: 31″L x 20″W x 54″H
  • You can remove platforms grille and bottom tray for convenient cleaning
  • Easy to assemble


  • The cage floor is covered with wires so I strongly recommend you make a tweak to the cage floor if you buy it. Walking on the wires all the time can hurt rats’ feet and cause a condition called bumblefoot. Plus, these wires are too far apart for them to walk normally. Some rat owners recommend putting the tiles on the cage floor, or you can put some kind of metal panel (but make sure it is not sharp on the edges).

Kaytee My First Home Rat Cage

Kaytee cage is a bit smaller than the ones above but it still has plenty of room for the rats to run around. It includes safety ramps, spiral slide, hammock, something called FerreTrail Fun-nel, and 3 comfort shelves. It’s like a small amusement park in there! Bar spacing of 1’’ makes it suitable for adult rats but not for babies or smaller rats.


  • Easy to clean
  • Replaceable parts available
  • Interactive environment that will keep rats entertained
  • Plenty of room: 24 x 24 x 41.5 inches


  • Low-quality hammock material and low-quality plastic

The best rat cages for baby rats or 2 adult rats

As I mentioned, baby rats need a cage with bar spacing of 1/2” or less. Anything wider than that and they will be able to squeeze out of the cage. Here are 2 great rat cages that the baby rats won’t be able to escape from. These cages are smaller so they can also be used if you only have a few rats.

Critter Nation Single Story Cage

Critter Nation Single Story Cage

Critter Nation Single Story Cage – check current price on Amazon

This is the same cage as the Critter Nation cage listed above but this is a single story version. If you’re looking for a great rat cage for a lower cost or one that occupies less room, this might be for you.

Although I always prefer choosing a bigger cage so the rats can have plenty of space to run around, if your apartment can’t hold a big 2 story cage, this one is a great option too. It works great for baby rats or a small number of adult rats. It has one pan, one adjustable shelf and one ramp with cover.


  • Full-width double doors make it easy to clean
  • Sturdy and durable material
  • Can be easily transferred through the room with 4 locking wheel casters
  • 1/2″ bar spacing makes it easy for adult and baby rats to climb and explore without an escape option
  • Solid floor base won’t cause issues for the rats’ feet
  • Rats will have enough room: 36″L x 25″W x 38.5″H
  • 1-year manufacturer’s warranty


  • Can be hard to assemble

Kaytee My First Home Habitat Multi-Level for Exotics

Kaytee My First Home Habitat Multi-Level

Kaytee My First Home Multi-Level Cage – check current price on Amazon

This is the smallest rat cage on our list and it can hold up to 4 rats (although we always recommend getting a bigger cage if you have more than 2 rats). It has multiple levels that promote healthy activity and a few solid plastic shelves and ramps to entertain the rats. This cage is alright but if you can’t make up your mind between this one and the Critter Nation Single Story cage from above, I would go with the Critter Nation as it is more spacious and of better quality.


  • It has a deeper base so bedding and litter won’t spill out of the cage
  • Suitable for baby rats because of the 1/2″ bar spacing so they can’t escape
  • Enough room for up to 4 rats max: 30.5 x 30.5 x 18.5
  • Cheaper price


  • Some people had issues with their rats chewing through the plastic bottom and escaping so this cage might not be the best choice if your rats like to chew through everything
  • Not that easy to clean


Buying a large rat cage with plenty of room for your rats is great but your job is not done here. You’ll have to enrich the cage interior with plenty of toys and fun supplies that will keep your pets entertained. A large empty cage is just as boring as a small cage so provide these additions in your rat cage:

Btw you might also want to read some of our tips and ideas for a rat cage setup.

And don’t forget one thing – make sure to let your rats out of the cage for at least 1 hour every day so they can roam and explore the “outside” world inside your home. Rats can’t get enough of exercise if they are locked in their cages 24/7. Plus, they will be a lot happier if they can play outside of the cage every day.

Choosing the best rat cage should be taken seriously. After all, your pet’s quality of life depends on it. I hope these tips and recommendations helped you choose the best cage for your rat.
