Before adopting Hamster

While small and easy to keep, they are small animals with a short lifespan of around 2-3 years. Early detection through careful observation of health changes that can worsen suddenly—such as wet tail (diarrhea)—and appropriate temperature control are important.

What to check before adopting

Understanding a Short Lifespan
Medium
Hamsters have a short lifespan of around 2–3 years, so you must be prepared to cherish the limited time you have together. Confirm that you can provide responsible care from beginning to end.
Attention to Wet Tail and Diarrhea
High
Wet tail caused by bacterial infection and similar conditions can lead to diarrhea and may be life-threatening. If you notice soiling around the rear end or diarrhea, seek veterinary care promptly. Creating a low-stress environment also contributes to prevention.
Breeding environment and temperature.
High
Because hamsters are sensitive to heat and cold, proper temperature management is essential. Provide a cage equipped with a wheel and bedding material, and confirm that most species require solitary housing.
Tameness and Stress
Low
Hamsters are nocturnal, and excessive handling causes stress. Confirm that you can gradually and gently acclimate your hamster to handling.

Key points to check

Check the Rear End and Feces

Good:: The area around the rear end is dry and clean, and feces maintain their shape.
Caution:: A wet rear end or diarrhea may indicate wet tail; seek veterinary care promptly.

Check Fur and Eyes

Good:: Fur is dense and lustrous, eyes are clear, and the hamster is moving actively.
Caution:: Hair loss, eye discharge, or sluggish movement are signs to check overall health.

Check Teeth and Appetite

Good:: The hamster eats well, and the front teeth alignment is normal.
Caution:: Poor appetite or excessive drooling may indicate dental or health issues.
