Optimum care for your rats keeps them healthy and strengthens your bond. Here are the five essentials for pet rat health and happiness:
1. Diet: What Do Pet Rats Eat?
What’s the best diet for pet rat health?
The best diet combines a high-quality commercial food with fresh fruits and vegetables.
The most trusted commercial diets are:
Young rats need more protein, while older rats need less. Mazuri contains 23% protein, which is great for babies but less ideal for adults. Oxbow and Harlan Teklad offer formulas for different life stages. You can find Oxbow in some pet stores, but all of these diets are available online (see links above).
What fruits and vegetables can rats eat?
Bok choy, kale, and broccoli are excellent options. Organic produce is best. Many owners also add tofu, soybeans, and/or miso to support female rats’ health.
I also recommend Green Mush, a superfood supplement. Since I started using it, my rats have lived almost twice as long.

2. Environment: Your rats’ cage and free-range room
How do I set up the best cage for pet rat health?
- Choose the largest cage you can afford and have space for. Find details on choosing a cage for your rats on Pet Rat Cages: Find the Perfect Palace.
- Place the cage in a quiet, ventilated room where you spend time
- Spot-clean daily, deep clean weekly
What location is best for my pet rats’ cage?
- Keep the cage in a quiet, well-ventilated room where you spend time.
- Keep it away from cats and dogs.
- Maintain a comfortable temperature.
What enrichment helps maintain pet rat health and happiness?
Rats thrive on variety. Inside the cage, rotate:
- Hammocks and chew toys
- Ladders and wheels
- Hideouts and nesting materials
In their free-roam space, offer mazes, boxes, paper bags, and safe climbing areas. Regularly change things up so they always have something new to explore. Read Making a Room Safe for Your Pet Rats to keep your rats out of danger while they’re outside their cage.
Can scented products harm pet rats?
Yes. Candles, incense, and air fresheners can irritate their sensitive lungs. Stick to unscented products.
Enrichment is all about engaged interactions—whether it be with you, other rats or with their environment. Make changes regularly so they continually have new things to explore.
3. Veterinary Care: For Pet Rat Health, Do Rats Need a Vet?
Why is a rat-savvy vet so important for pet rat health?
Rats have illnesses that are vastly different than those of dogs or cats. A qualified vet can catch issues early and help you maintain their health.
How often should rats see a vet?
- First exam: within one week of adoption
- Routine exams: every 6 months (more often for seniors)
- Emergency exams: whenever your rat is injured or sick and your regular vet isn’t open. For a list of symptoms that need more immediate attention see When to See a Veterinarian.
👉 Pro tip: Have more than one vet available—your regular doctor won’t always be on call.
Should female rats be spayed?
Yes. Spaying helps prevent mammary tumors, one of the most common rat health issues. Early spaying is best, but it can also be done if a tumor develops.
Should male rats be neutered?
Yes. Neutering helps curb hormonal aggression, ensuring a more harmonious household. Neutered rats are less likely to urine mark, develop buck grease, get testicular cancer or develop urogenital conditions.
4. Time Together: How Much Time Do Pet Rats Need?
Rats are social animals and need daily interaction. Aim for at least two sessions a day. Ideally each session should be around an hour. Thirty minutes per session is the minimum amount if you’re pressed for time.
Easy ways to spend time with your rats:
- Let them sit on your shoulder while you get ready for your day
- Have them with you while you read, watch TV, or fold laundry
- Bring them along on safe errands or vacations (see On the Road with Rats)
Including them in your daily routines helps them stay confident and bonded with you.
5. Individual Attention: Why Knowing Your Rat Matters
Every rat has a unique personality. Some love cuddles, others prefer playing or learning tricks.
Why one-on-one time is so important:
- Strengthens your bond
- Helps you notice health changes like lumps, scabs, or injuries
- Makes it easier to spot behavior changes that may signal illness
Treat each rat as an individual, and they’ll thrive.
