📏 Physical Differences at a Glance

• Hamsters: More robust body, short stubby tails (< 1 cm), size varies by species (2–7″) :contentReference[oaicite:3]{index=3}.
• Gerbils: Sleek build, long furry tails (~body length 4–7″), leaner appearance :contentReference[oaicite:4]{index=4}.

🧬 Lifespan & Health Basics

• Hamsters: Typically 2–3 years (up to 4 for dwarfs) :contentReference[oaicite:5]{index=5}.
• Gerbils: Live slightly longer at 3–5 years :contentReference[oaicite:6]{index=6}.
• Gerbils less prone to obesity but occasionally experience epilepsy and tumors; hamsters often face dental issues and respiratory disease :contentReference[oaicite:7]{index=7}.

🤝 Social & Behavioral Traits

• Hamsters: Mostly solitary—can be territorial and aggressive, especially Syrians; nocturnal or crepuscular; low activity during day :contentReference[oaicite:8]{index=8}.
• Gerbils: Social by nature—enjoy pairs/groups; crepuscular and active during day; curious, playful, often less prone to biting :contentReference[oaicite:9]{index=9}.
• Reddit consensus: gerbils are “more curious and fun” and “less smelly” than hamsters :contentReference[oaicite:10]{index=10}.

🏡 Housing & Habitat Needs

• Hamsters: Prefer single-level enclosures to avoid falls; need burrowing-friendly substrate; less social enrichment :contentReference[oaicite:11]{index=11}.
• Gerbils: Thrive in multi-level setups with deep bedding for digging; active and need height to explore :contentReference[oaicite:12]{index=12}.
• Both need solid floors, secure housing, chew toys, exercise wheels, hideouts, and regular cage cleaning.

🧵 Daily Care & Handling

• Hamsters: Low-maintenance but need gentle, age-appropriate handling; more prone to bite if startled or mishandled :contentReference[oaicite:13]{index=13}.
• Gerbils: Generally friendlier; enjoy social interaction; quick and agile so supervision during handling is key :contentReference[oaicite:14]{index=14}.
• Shedding and grooming needs are minimal for both species.

🥗 Diet & Nutrition

• Omnivorous diets recommended: high‑quality pellets, fresh vegetables, occasional protein treats.
• Gerbils may need lower-fat diets to avoid obesity; hamsters benefit from dental wear via chew items.
• Avoid sugary or sticky foods; fresh produce uneaten after 12 hrs should be removed.

🩻 Veterinary Considerations

• Hamsters: Watch for wet tail (diarrhea), respiratory infections, dental overgrowth, tumors.
• Gerbils: Monitor for epileptic seizures, tumors, tail-slip infections, Tyzzer’s disease, ear problems :contentReference[oaicite:15]{index=15}.
• Regular vet checkups recommended for both—ideal at least annually or if symptoms arise.
