If you are a genuine animal lover, you don’t have to limit yourself to loving only one or two different types of pets. There are animals that also deserve to be loved just as much such as rats. Although rats as pets may sound eccentric to some, know that these tiny creatures are fun to be around provided that you are properly taking care of them. Rats are social, smart, and full of quirks!
Domesticated rats are far from being the vermin that most people thought they are. Taming rats is an easy and enjoyable task. Therefore, they can be incredible pets, especially for those who are busy as a beaver. They also have their own idiosyncrasies just like dogs and cats.
Although taking care of domesticated rats sounds much easier than taking care of larger animals, that doesn’t imply that they are low-maintenance. Rats need your tender loving care and attention. Regardless how busy you are, you need to devote a fair amount of time to play with your tiny critter; an hour each day would be ideal. But before you adopt a rat, you need to make sure that there is a secure and comfortable rat habitat waiting for him.
Buying your rat a good quality cage is the first step to achieving a healthy and happy life. Since there are too many to choose from, we made a list of the leading rat cages in the market today. To make it even easier for you, we also provided a buying guide so you will know what you are looking for.

Buying Guide: Factors to Consider When Buying a Rat Cage
You need to provide your whiskery friend with a habitat that has the conditions necessary to make him feel safe, happy, and comfortable under your roof. The following are the critical factors you need to think about before you make a purchase.
1. Size of the Cage
According to some rat owner’s blog, at least 2 cubic feet of space is recommended for each rat but we suggest otherwise. Your tiny critter is going to live his entire short life in an enclosure and hence it would be best to make it as comfortable as possible. The short and long of it is choosing the largest cage you can get your hands on as long as it won’t pose an inconvenience to your house.
The only way your whiskery friend can enjoy various perks is to have a large cage. While male rats or bucks prefer more ground space, female rats or does prefer more height so they can climb up as often as they want. With a large cage, you can add toys and paraphernalia to keep him entertained. You can place a hammock, a tunnel a digging box, a bean bag, his very own clubhouse, or all of these.
Nonetheless, you may opt for a smaller rat cage if you only need to house kittens or baby rats. Bear in mind that you need to transfer them once they grow; otherwise, they won’t have the appropriate space they need to move around and play. It is more economical to choose a rat cage that can accommodate their needs even when they grow into full adults.
Take note that rats are originally forest creatures that live in harmoniously large groups. Among all rodents, rats are the most social. Therefore, it would be wise to adopt at least a pair of rats instead of just one.
2. Accessibility and Ease of Cleaning is a Must
Take a closer look at the cage’s doors. Its doors should be wide enough for you to reach in and take out your pet. If you opt for a full-width door, the better. Such feature prevents you from squeezing yourself into an opening just to interact with your pet. A full-width door also paves the way for quick and easy cleaning.
3. The Cage Should Provide Maximum Visibility and Ventilation
Fish tanks and plastic enclosures are the worst dwellings you can ever bestow your pet rat as these items easily build up ammonia and air contaminants, which could greatly affect your pet’s respiratory health. Likewise, these dwellings build up humidity and temperature quite fast.
Rats are highly susceptible to respiratory illnesses and hence, they need a well-ventilated cage. Glass and plastic enclosures isolate bad air quality and thus, foul smell and contaminants will linger much longer. Although some plastic cages may seem acceptable, choosing an all-metal cage would be the best option.
4. Take Note of Its Design
A cage’s design is not just a trivial factor as it defines the level of comfort your pets get from its shelter. It is imperative that your cage exhibits a solid flooring to hold paper or fleece bedding. This could be heavy-duty plastic or PVC covered metal. Wire grates may seem beneficial as it allows pet waste to just fall through and hence, your fancy rat doesn’t have to step on his own poop. However, wire floors increase the risk of your tiny fellow from slipping his feet between the mesh flooring. Not only will this cause sprains but also serious damages to his tiny feet that may require amputation.
Having his feet constantly pressed against wire causes a condition called bumblefoot, which is characterized by painful sores and swellings that could become infected. If you don’t want your pet hurting, then choose a cage with solid flooring.
Moreover, take a closer look on its shelves and ramps. Both should be organized in a way where you can easily adjust them especially. Most importantly, make sure the ramps have a textured surface for traction so your pets won’t slip as they climb up.
5. Focus on the Level of Security it Provides
While you opt for a cage that provides you with an easy access to all its parts, make sure its door will also remain tightly shut and inaccessible when you mean to close it. A cage is completely useless if it can’t contain your pets. Rats are highly intelligent and hence, they can easily unfasten a feeble latch. If your pet rats can easily open the door, then the cage fails to serve its purpose.
Apart from its latch, check the gap between its bars. In general, the gap depends on the size of your pet rats. If you wish to get a temporary housing for your baby rats, then choose a cage that has ¼” bar spacing. It doesn’t matter if the cage has vertical or horizontal features. On the other hand, the most secure cages for adult rats and large rat breeds, have ½” bar spacing.
6. Materials Used can Make a Difference
A good quality cage may often cost a pretty penny but this is quite inevitable if you want something that could endure the ravages of time. With proper management, a good quality cage can be used for many rat generations. If you were to choose a metal cage with plastic components such as shelves, ramps, or pans, make sure these items are made of heavy-duty plastic that won’t thin out or crack after countless scrubbing or bleaching. Likewise, make sure the metal is rust-resistant. You may opt for a metal cage treated with a sleek powder or PVC coat. Although these finishes are prone to cracking and lose its touch, still they make the cage last much longer.
7. Your Cage Should be Portable
You’ll never know when you need to transfer your cage from one location to another. Therefore, your rat cage should have wheels so you can easily push it around your house. Also, assembling or dismantling the rat cage shouldn’t be that troublesome.
