Meet the pet rat

Social animals who thrive on interaction.

Domestic rats are intelligent, curious companions. They benefit from compatible rat company as well as regular, gentle interaction with their people.

Keep compatible pairs or small groups, with introductions planned carefully. Fighting can occur; watch for injuries, persistent chasing, or a rat being prevented from eating or resting.

Respect their routine: Rats are often most active in the evening and at night. Let sleeping rats wake before handling them, and support their bodies gently.
Daily care

Nutrition and an engaging home

Balanced meals

  • Use a complete rat-formulated block or pellet as the foundation of the diet.
  • Offer suitable vegetables and small amounts of fruit; keep seeds and other calorie-dense treats limited.
  • Introduce dietary changes gradually. Ask the team about portions rather than restricting protein or calories on your own.
  • Keep clean water available at all times. Inspect drinking bottles daily for blockage or leaks.

Housing and enrichment

  • Provide a spacious, well-ventilated enclosure with solid resting surfaces, safe levels, and hiding places.
  • Offer paper or cardboard for nesting, suitable climbing opportunities, and supervised activity outside the cage.
  • Use absorbent, low-dust bedding such as paper or aspen. Avoid strongly scented bedding and cedar.
  • Clean soiled areas regularly and protect rats from smoke, sprays, overheating, drafts, and abrupt temperature changes.
  • If using a wheel, choose a solid running surface large enough to avoid bending the back or tail.

Preventive care at every stage

EBH’s existing care guidance recommends physical examinations every 6–12 months, annual fecal checks, and blood testing as advised by the veterinarian. Your rat’s age and health may call for more frequent visits.

Bring recent weights, a diet list, and enclosure photos. Mention changes in breathing, appetite, activity, grooming, or mobility.

Discuss spaying or neutering and safe group composition with the team to prevent unplanned litters.

Veterinary awareness

Common health concerns

The original EBH portfolio highlights respiratory infections, dental problems, head tilt, obesity, kidney disease, salivary gland inflammation, parasites, and mammary tumors. Daily observation helps you recognize concerns early.

Noisy breathing or repeated sneezing
Drooling or difficulty eating
Head tilt or poor balance
New lumps or swelling
Weight or drinking changes
Itching, scabs or hair loss
Urgent concern? Labored or open-mouth breathing, collapse, severe weakness, or serious injury needs immediate attention. Call (904) 256-0043; do not wait for an online response. If unavailable, contact an emergency veterinarian that treats exotic mammals.

General education only; this guide does not replace individualized veterinary advice. Weight ranges are retained from EBH’s existing profile and are approximate, not target weights for every rat. Maturity refers to sexual maturity, not recommended breeding age. Lifespan and development vary.
