Best Rat Cages

We’re going to take a look at some of the best indoor rat cages in a moment.

Now let us take a look at why each cage is the best size for your rat(s).

How big does a rat cage need to be?

So, how big should a rat cage be?

There are many types of rat cages to choose from. The general rule of thumb for rat cage size is at least 2 cubic feet of space per rat. This is the minimum rat cage size.

If your pet rat is larger than average or you simply want to give your pet(s) more room to live in, which we recommend, you may choose to buy one with extra space.

Since the rat cage is where your rat will be living most of its life, erring on the side of a roomier cage is recommended.

It will give them more room to play in and hide and generally make for a happier living situation for your beloved pet.

Larger cages also encourage your rat to exercise more, possibly extending the life of your pet by reducing the likelihood of obesity related issues.

Also, if you have multiple pet rats, they will get along with each other better if there is ample room for them to spread out and have some private time as needed.

Another factor to keep in mind is the cages bar size. It should be ½ inch or narrower to prevent your pet rat(s) from escaping.

How big should a rat cage be for one rat? Rats should be kept with at least one other rat due to their high social needs. However, in the rare situation that a rat needs to be kept alone, either permanently or for a short time, you must choose a large enough cage.

When choosing a rat cage, you will want to purchase one that has proper ventilation.

The ones we recommend have wire bars on top and have a plastic or metal pan on the bottom to contain bedding.

Although at first glance it may seem like a good idea to get a rat cage with a wire bottom for droppings to go through, this is actually not good for your rats to walk on.

Walking on wire all the time may cause swelling and an infection, a problem called bumblefoot, which is certainly not something you want to have happen.

  1. You say wire bottom cages are bad for their feet, but some of the enclosures you recommend have wire bottoms. Are these wire bottoms removable?

    • As long as most of the shelves don’t have wire bottoms you should be fine, but we will still always put blankets (these need changing regularly) on the shelves that do have wire in them.

  2. Yeah, don’t get just one rat the fact that it was even put on here makes it think it’s an option for new rat owners that it’s ok to only have one rat. I’m very disappointed. Rats are social creatures and NEED to be in pairs minimum. Shame on you guys for spreading false care and essentially promoting neglect by putting that in here. DO NOT GET A LONE RAT. It’s abusive and neglectful to have a single rat when there is absolutely no need and actually negatively impacts their life and health. It’s way past the time of sharing harmful pet “care” that is very incorrect. Do better.
