Caring for Rats!

Whether you are preparing to adopt or simply researching proper husbandry, this guide is designed to walk you through the essentials of responsible rat ownership.

I recommend reading the beginners’ guide first and then exploring our more detailed articles about rat care. To skip the beginner’s guide, click here.

My goal is to make sure every Sundae Morning rat goes to a home that feels confident, prepared, and informed.

Beginner’s Guide to Pet Rat Care

A guide for new owners from Sundae Morning Rattery

Pet rats are intelligent, affectionate animals that thrive on companionship and interaction. With proper care, they become incredibly social pets that enjoy spending time with their humans. This guide covers the essentials of responsible rat ownership, including housing, diet, enrichment, health, and daily care routines.

Why Rats Should Never Live Alone

Rats are extremely social animals and should always live with other rats. In the wild and in captivity they form complex social groups and rely on companionship for mental wellbeing. Keeping rats alone can lead to loneliness, stress, and behavioral problems. For this reason, responsible owners keep at least two rats of the same sex, although small groups often work even better.

Housing and Cage Setup

Rats need a spacious enclosure that allows climbing, exploring, and sleeping comfortably.

A good rat cage should have:

  • Multiple levels

  • Solid floors (not wire)

  • Good ventilation

  • Secure doors and narrow bar spacing

  • Plenty of climbing opportunities and clutter to feel safe

Rats are active animals, and larger cages significantly improve their welfare. Many care guides recommend at least 2 cubic feet of space per rat, though more space is always better.

Cage Setup Essentials

Your rats’ enclosure should include:

  • Hammocks

  • Hideouts

  • Climbing ropes or ladders

  • Chew toys

  • Litter box

  • Nesting material (paper, tissues, etc.)

Providing different textures and climbing options helps keep rats mentally stimulated.

Safe Bedding

Rats have sensitive respiratory systems, so choosing the right bedding is important. You should set up your enclosure to allow for deep bedding, between 2 - 4 inches deep.

Safe options include:

  • Aspen or kiln-dried pine bedding

  • Hemp bedding

Avoid:

  • Cedar

  • Pine

  • Dusty bedding

  • Fleece/blankets

  • Paper

These materials can either release harmful aromatic oils or allow ammonia buildup that will irritate the respiratory system.

Diet and Nutrition

Rats are omnivores and thrive on a varied diet that includes a balanced staple food plus fresh foods.

Staple Diet (Lab Blocks)

The majority of a rat’s diet should be a high-quality lab block or pellet designed specifically for rats.

These foods provide balanced nutrition and prevent rats from picking out only their favorite foods.

Common examples include:

  • Oxbow Essentials Adult Rat Food

  • Mazuri Rat and Mouse Diet

  • Teklad/Harlan lab blocks

Staple foods should make up the majority of a rat’s diet, with fresh foods offered as supplements.

Fresh Foods for Rats

Fresh foods provide enrichment and additional nutrition.

Good options include:

Vegetables

  • Broccoli

  • Kale

  • Carrots

  • Peas

  • Bokchoy

Fruits (in moderation)

  • Apples

  • Bananas

  • Berries

Protein treats

  • Eggs

  • Cooked chicken

  • Plain lactose free yogurt

Rats should always have access to fresh water from a water bottle.

Foods That Rats Should Not Eat

Some foods can be unsafe for rats and should be avoided. There are much more thorough lists online that you should read up on, although there is sometimes disagreement about what is and is not safe for rats. (I will make an all encompassing list soon!)

These include:

  • Raw beans

  • Alcohol

  • Caffeine

  • Very salty or sugary foods

  • Lactose

  • High fat foods (too many seeds, oils etc)

Feeding a balanced diet and limiting treats helps prevent obesity and health problems.

Enrichment and Mental Stimulation

Rats are extremely intelligent animals and require enrichment to stay happy.

A well-enriched cage may include:

  • Hammocks

  • Tunnels

  • Climbing ropes

  • Foraging toys

  • Wooden chew toys

  • Dig boxes

Rats should also receive daily out-of-cage exercise time to explore and interact with their owners. One hour per day minimum, the more the better! (As long as they have food and water available)

Without mental stimulation, rats can become bored or stressed.

Handling and Socialization

Most rats become very affectionate pets when handled regularly.

Tips for bonding with your rats:

  • Allow new rats a few days to settle into their new home

  • Use treats to build positive associations

  • Always support their body when lifting them

  • Never pick up a rat by its tail

  • Handle them with confidence, pick them up when needed, but also give them opportunities to choose to come to you

  • Have a dark cozy spot for them to settle, like a hoodie pocket or blanket so they feel safe with you

Regular handling helps build trust and strengthens your bond.

Health and Veterinary Care

Rats have short lifespans, but this does not mean you will find them passed away in their cage at the end of their life (it can happen, but it’s not typical). Rats are fighters and will hide infection and illness for as long as possible. It’s important to do daily health checks on your rats to catch illness early for the best chance of treatment.

Rats have very sensitive lungs and noses. You should never have candles, diffusers, fragrance, essential oils or Febreze where your rats may smell them. I also recommend using fragrance free dish soap to clean their cages to avoid irritation. I recommend having an air purifier, not because they are stinky, but because it helps filter out all of our toxins for them! Even all purpose cleaners can bother them. If you can smell it, they can smell it much, much more!

Common health issues include:

  • Respiratory infections

  • Tumors

  • Parasites (mites)

  • Abscesses, cuts and scrapes

  • Dental issues

  • Soft stool or changes in stool

Signs of illness may include:

  • Sneezing or noisy breathing

  • Weight loss

  • Lethargy

  • Lumps or swelling

  • Red discharge around the eyes or nose

  • Squinted eyes, side sucking

If you notice any of these symptoms, consult an exotic animal veterinarian.

How to do a health check

  • Weigh your rat on a kitchen scale. Record weight in grams. For adult rats, they should not be rapidly dropping or gaining weight.

  • Pet your rats with firm pressure, pay attention to the spine and hips. They should feel strong and stable. Watch for the spine feeling bony and/or thinning of skin.

  • Pick up your rat and look at their eyes. They should be wide open, bright, and shiny all over. Beware of dullness, discharge, crusties, injury, etc.

  • Check ears by looking into them for any discharge, and even smelling them for any signs of infection. If there is something wrong you may smell it. Feel around the jaw and under the ears for any swelling.

  • Hold the rat up so the side of their ribs is touching your ear. This is called Rat Phone. Listen to what their breathing sounds like every day. This will help you learn what their normal is, and you’ll notice if things change. It should sound like a whooshy helicopter. You shouldn’t hear any crackling, bubbling. popping, wheezing etc.

  • Lift rat up above you so you can see the mouth, and gently pull on the chin skin to look at the teeth. They should be flat across both ends of the teeth, not skewed or angled.

  • Feel down the sides of the rat for any lumps or bumps.

  • Look at the feel and nails and make sure they are clear of injury.

  • Check the genital area and tail for any swelling or injury. Rats keep themselves very clean, there should not be any residue around their genital area. For males, especially older males, you may need to slide back the sheath of the penis to make sure there is no buildup.

  • Put your rattie down and watch their behavior. A healthy rat will be bright, move confidently, sniff around and not make any breathing sounds. They should not wobble or have a head tilt. They should be able to sit up and hold their food tightly with two hands.

If anything comes up during your health checks, be sure to call your vet and get an appointment for your rat!

Daily and Weekly Rat Care Schedule

Many new owners wonder what daily care actually looks like. While routines vary, caring for rats usually involves a combination of daily interaction and routine cage maintenance. Below is a typical routine used at Sundae Morning Rattery.

Daily Routine

Morning:

  • Check food and refill lab blocks if needed

  • Refresh water bottles

  • Remove any spoiled food

  • Rat medicine, if necessary

Evening

  • Refill lab blocks and add fresh food

  • Spot clean cages

  • Free roam and social time, minimum 1 hour of supervised out-of-cage time

  • Health checks

  • Rat medicine, if necessary

Rats benefit greatly from daily interaction and exercise outside their enclosure.

Every Other Day

  • Change litter boxes

  • Replace or wash hammocks

  • Remove heavily soiled bedding

Rats tend to use certain areas more frequently, so these spots may need more frequent cleaning.

Weekly

Once per week:

  • Remove all bedding

  • Wash cage surfaces

  • Clean shelves and accessories

  • Replace bedding

  • Wash hammocks and fabric items

  • Order groceries with fresh food items in mind for the rats

Complete cage cleanings help prevent ammonia buildup from urine, which can irritate rats’ respiratory systems.

Introducing New Rats

When adding new rats to an existing group, introductions should be done carefully to avoid conflict.

Summary of rat introductions:

  1. Quarantine new rats for 2 weeks in a separate room

  2. Introduce rats in a fully cleaned, small carrier with supervision

  3. After rats relax and are sleeping in carrier (a few hours hopefully), move rats into a slightly bigger cage (also ensure it is fully cleaned to avoid any old scents).

  4. Once rats fully show bonding behavior (rat piles, snuggling, etc) they can be moved up into a larger cage. This entire process may take a few days to a few weeks, no need to rush.

  5. Move rats to full size, fully cleaned cage.

Some minor squeaking and pinning is normal as rats establish hierarchy. Please do lots of research before introducing rats, as this quick summary is an example of one method.

Free Roam Safety

Before allowing rats to explore outside their cage, the area should be rat-proofed.

Make sure to:

  • Cover electrical cords

  • Block small holes or gaps

  • Remove toxic plants

  • Keep other pets away

Rats are natural chewers and can fit through surprisingly small spaces.

Choosing a Responsible Breeder

A responsible breeder focuses on health, temperament, and proper socialization.

Good breeders typically:

  • Handle babies appropriately

  • Select for temperament

  • Provide lifelong support to adopters

  • Offer guidance on care and introductions

  • Maintain clean housing and proper nutrition

Ethical breeders also ensure rats are placed in appropriate homes and are never adopted out alone.
