How Much Does a Rat Cage Cost?

The price of a rat cage varies between $30-180, depending on the size. Some cages can already come with a few accessories, such as water and food bowls, stairs, or toys.

A rat cage can be up to $180 or more, depending on its size. 

Rats are good at escaping, which is why it is ideal to buy a cage with a small space between the bars.

Rats also like to chew anything, so the cage material should be hard (metal or plastic). Avoid the following enclosures:

  • Cages made of wood or soft metal
  • Cardboard boxes
  • Aquariums
  • Terrariums

Tips for Building Your Pet Rat Enclosure

To make the perfect rat enclosure, you need a sturdy cage, recycled paper bedding, hiding places, and chewing toys. The space between the cage bars must be small. Pet rats are known for their ability to escape. The material of the cage must be hard so that it cannot be chewed.

Choose a cage as large as possible for the rat. The basic rule is at least 2 cubic feet of space per rat. Most pet rats spend 22-23 hours a day in their cage, so it should be large enough for them to explore.

Rodents tend to gnaw continuously on their cage, so stainless steel, hard plastic, or wire cages are recommended. Avoid cages made of wood or soft metal.

Cages with hard plastic floors and closed metal bars are ideal in terms of pet insulation, as well as in terms of ventilation.

Avoid terrariums as they do not provide adequate ventilation.

You also need to purchase several accessories for your rat’s cage:

  • Bedding
  • Toys and exercise accessories
  • Wooden blocks
  • Calcium blocks
  • Thermometer

Pet rat Bedding

Provide your new pet rat with enough material to build a nest. Use bedding that will be able to retain, cover, and absorb urine. A clean, absorbent, non-toxic, and odorless substrate is the best way to go. 

Products based on recycled paper are the best substrates for bedding.

Toys & Chewing Instruments

You also have to provide tunnel toys, running wheels, and boxes to maintain your pet’s mental health. Buy some cardboard rolls, wood blocks, and calcium blocks for chewing. Rats’ teeth grow continuously, so they need something to gnaw on.


The optimum ambient temperature for rodents is between 18-26°C (64-79°F), with a relative humidity of 40-70%. Place a thermometer on the cage to keep track of the temperature.

Place your rat’s cage out of direct sunlight and away from other heat sources such as radiators.


Thoroughly clean your pet’s cage and its attachments once or twice a week. Change the bedding and disinfect the entire surface of the cage. Clean the food and water containers regularly.

Tips for Keeping More Rats Together

Rats are sociable animals. 

Adult males should be separated if they do not come from the same generation or if they did not grow up together. 

Females or pairs of different sexes get along well. If pairs of different sexes live together, sterilize the males, as rats are a prolific species.
