Overview
Pet rats are, without question, one of the most underrated companion animals in the small pet world. Fancy rats and hairless rats are highly intelligent, deeply social, and capable of forming genuine bonds with their owners — learning their names, coming when called, and even mastering tricks. They're often described as "dogs in a small package" by devoted rat owners, and for good reason.
At Ohio Pet Depot, we carry two varieties of pet rats:
- Fancy Rat - Juvenile — $14.99 — the classic domesticated rat, available in a wide range of colors and coat patterns; curious, playful, and highly trainable
- Hairless Rat — $24.99 — a unique variety with little to no fur; identical in temperament to fancy rats but with special care considerations for temperature regulation and skin health
With proper care, pet rats live 2–3 years — a shorter lifespan than many pets, but one filled with personality, affection, and entertainment. Many rat owners find themselves completely hooked after their first pair.

Social Needs — Rats Must Have Companions
Rats are highly social animals and should never be kept alone. A solitary rat is a stressed, depressed rat — they rely on companionship for grooming, play, warmth, and emotional wellbeing. Always keep at least two rats together, ideally same-sex pairs or groups introduced at a young age.
- Same-sex pairs are the easiest starting point — two females tend to be more active and playful; two males are often calmer and more cuddly once past adolescence
- Males can be more territorial during adolescence (4–8 months) but typically mellow significantly after neutering or with age
- Introducing new rats requires a slow, neutral-territory introduction process — never just drop a new rat into an established cage
- Rats from the same litter or introduced young generally cohabitate with minimal conflict
Housing & Cage Setup
Rats are active, climbing animals that need vertical space as much as floor space. A multi-level wire cage is ideal — aim for at least 2 cubic feet per rat, with bar spacing no wider than ½ inch for females and small males (1 inch max for large adult males). Avoid aquariums — they have poor ventilation and trap ammonia from urine, which damages rat lungs over time.
Cage Essentials
-
Bedding — line the bottom of the cage with safe, absorbent bedding:
- Kaytee Clean & Cozy Paper Bedding (24.6 L) — $12.99 — soft, dust-free, and highly absorbent; our top pick for rats
- Kaytee Aspen Small Animal Bedding (20L) — $9.99 — safe natural wood option. Never use cedar or non-kiln-dried pine — the aromatic phenols cause serious respiratory damage in rats
-
Exercise wheel — rats love to run, especially females. Use a solid-surface wheel only — wire wheels cause tail and foot injuries:
- Kaytee Comfort Exercise Wheel — $14.99 — solid running surface, good size for rats
- Kaytee Silent Spinner Wheel — $16.99 — quieter option for light sleepers; solid surface design
- Hideout — rats need enclosed sleeping spots. The KAYTEE Natural Tree Trunk Hideout ($7.99) provides a cozy, chewable den
- Hammocks and hammock-style beds — rats adore sleeping in hammocks; fleece hammocks hung at multiple levels are a staple of any well-set-up rat cage
- Chew toys — the Kaytee Nut Knot Nibbler (Medium) ($8.99) satisfies their need to gnaw and keeps teeth worn down
- Food dish — the Kaytee Cool Crock (Small) ($3.99) is a tip-proof ceramic crock that works perfectly for rat kibble
- Litter pan — rats are naturally clean and will often choose one corner to eliminate in. Place a KAYTEE Hi-Corner Litter Pan filled with Kaytee Critter Litter ($11.99) in that corner to make cleaning much easier
Temperature & Environment
| Parameter | Ideal Range |
|---|---|
| Ambient Temperature | 65–80°F (18–27°C) |
| Heat Danger Zone | Above 85°F — rats are susceptible to heat stroke |
| Humidity | 40–70% |
| Drafts | Avoid — especially critical for hairless rats |
| Ventilation | Essential — wire cages only; no aquariums |
Hairless Rat Special Considerations
Our Hairless Rats ($24.99) are identical in personality and intelligence to fancy rats, but their lack of fur creates a few unique care requirements:
- Temperature sensitivity — hairless rats cannot regulate body temperature as effectively as furred rats. Keep their environment at the warmer end of the range (75–80°F) and provide extra fleece bedding, hammocks, and snuggle spots. Avoid drafts entirely
- Skin care — hairless rat skin can become dry or irritated. Check regularly for cuts, scrapes, or redness — their skin is more exposed to cage surfaces and cage-mates' nails. Avoid rough or abrasive bedding
- Soft bedding is essential — use Kaytee Clean & Cozy Paper Bedding ($12.99) as the primary substrate; it's the gentlest option on bare skin
- Immune considerations — hairless rats may have slightly more sensitive immune systems; keep their environment clean and monitor closely for early signs of illness
- Companionship — hairless rats benefit especially from cage-mates for warmth; a furred companion can help them stay warm during sleep
Diet & Nutrition
Rats are omnivores and thrive on a varied diet. A quality lab block or rat-specific pellet should form the base of their diet, supplemented with fresh foods.
Recommended Diet
-
Quality rat food (base diet) — we carry two great options:
- Kaytee Forti Diet Pro Health Mouse & Rat Food (3 lb.) — $11.99 — a fortified daily diet with added vitamins and minerals; solid everyday staple
- KAYTEE Fiesta Gourmet Variety Diet Mouse & Rat Food (2 lb.) — $11.99 — a variety mix with fruits, veggies, and grains; great for enrichment feeding and foraging
-
Fresh foods (daily supplement) — rats love and benefit from fresh food variety:
- Vegetables: broccoli, peas, kale, romaine, cucumber, bell pepper, cooked sweet potato
- Fruits (small amounts): apple (no seeds), banana, blueberries, strawberries
- Protein: small amounts of cooked chicken, scrambled egg, or mealworms
- Grains: cooked pasta, brown rice, whole grain bread as occasional treats
- Treats — the Kaytee Healthy Bits Small Animal Treats ($6.99) and Vitapol Smakers Treat Stick - Fruit ($2.49) work well as training rewards and enrichment
Foods to AVOID
- Raw beans and raw sweet potato (contain harmful compounds when uncooked)
- Green banana (contains enzyme inhibitors)
- Citrus fruit for males (d-limonene linked to kidney cancer in male rats)
- Chocolate and caffeine (toxic)
- Alcohol (toxic)
- Onion and garlic (toxic)
- Carbonated drinks (rats cannot burp — gas buildup is dangerous)
- Sticky foods like peanut butter in large amounts (choking hazard)
Fresh water must be available at all times via a sipper bottle or heavy ceramic bowl, cleaned daily.
Enrichment & Mental Stimulation
Rats are among the most intelligent small animals kept as pets — they need mental stimulation as much as physical exercise. A bored rat is a destructive, unhappy rat.
- Daily free-roam time — at least 1–2 hours outside the cage in a rat-proofed space. Rats will explore every inch of a room and chew anything accessible — cover wires and block gaps before letting them out
- Foraging — hide food in paper bags, cardboard tubes, or scatter it in bedding to encourage natural foraging behavior
- Training — rats can learn to come when called, navigate mazes, retrieve objects, and perform tricks. Use small food rewards and short, positive sessions
- Rotate toys — swap out toys and rearrange the cage layout every 1–2 weeks to keep the environment novel and stimulating
- Cardboard boxes and tubes — free enrichment; rats love to shred, tunnel, and nest in cardboard
Handling & Bonding
Well-socialized rats are gentle, curious, and genuinely enjoy human interaction. Hand-raised juveniles like ours are already comfortable with people — your job is to build on that foundation.
- Let new rats settle for 24–48 hours before handling; offer treats through the cage bars first
- Scoop rats from below rather than grabbing from above — overhead grabs trigger prey instincts
- Support the full body; never pick up by the tail — this causes pain and can injure the tail
- Handle daily for at least 15–30 minutes to maintain tameness and strengthen the bond
- "Boggling" — rapid eye vibration — combined with bruxing (tooth grinding) is a sign of deep contentment, like a cat's purr
Health & Common Issues
| Condition | Signs | Action |
|---|---|---|
| Respiratory Infection (Mycoplasmosis) | Clicking/wheezing breathing, red discharge around nose/eyes (porphyrin), lethargy | Vet immediately — Mycoplasma is endemic in rats; manage, not cure |
| Mammary Tumors (females) | Lumps under skin, especially along belly/chest | Vet — very common in unspayed females; often benign but grow rapidly |
| Pituitary Tumor | Sudden hind leg paralysis, head tilt, loss of coordination | Vet — common in older rats; palliative care options available |
| Skin Infections / Wounds (hairless) | Redness, scabbing, open sores on skin | Vet — hairless rats are more prone to skin issues |
| Obesity | Visible fat deposits, reluctance to move | Reduce high-fat treats; increase exercise and fresh vegetables |
| Ear Infection | Head tilt, loss of balance, scratching at ears | Vet — treatable with antibiotics |
| Bumblefoot | Swollen, red, or ulcerated feet | Vet — caused by wire flooring; use solid-surface cage floors and soft bedding |
Porphyrin — the red discharge around a rat's nose and eyes is not blood — it's a pigmented secretion that increases with stress or illness. A small amount is normal; heavy, crusty buildup is a sign something is wrong and warrants a vet visit.
Find a rat-savvy exotic vet before you need one. Rats decline quickly when ill — by the time symptoms are obvious, conditions are often advanced. Schedule a wellness exam within the first 30 days.
Signs of a Healthy Rat
- Bright, alert eyes with minimal porphyrin discharge
- Smooth, well-groomed coat (fancy rats); clean, unbroken skin (hairless rats)
- Active and curious, especially at dawn and dusk
- Eating and drinking regularly
- Bruxing and boggling during handling — signs of contentment
- Running on the wheel and engaging with enrichment
