Hibernation:
Hamsters sometimes go into hibernation-like state if the temperature becomes too low. When they hibernate, their body temperature drops, and they appear immobile. Check your hamster's cage temperature and ensure it's within the recommended range for their species (usually between 65-75 degrees Fahrenheit). If it's too cold, gradually warm up the environment using a heating pad or other safe heating source.
Stress:
Sudden and prolonged changes in their environment can stress hamsters, causing them to become immobile. If you left the hamster alone for an extended period without their usual routine or sufficient food and water, this could have led to severe stress. Offer your hamster fresh food and water, and provide a quiet, undisturbed environment to rest and recover.
Illness:
Paralysis can also be a sign of an underlying medical condition, such as a neurological issue or internal injury. If you suspect illness, it's essential to consult a veterinarian with expertise in small animal care as soon as possible.
Injury:
Hamsters can sustain injuries if they fall or get trapped somewhere in their cage. Check for any signs of external injuries, such as wounds or broken bones. If you find an injury, seek veterinary care immediately.
While you wait for veterinary attention, keep your hamster in a warm, quiet, and dark area. Provide access to fresh food, water, and bedding material. Avoid handling or disturbing them unnecessarily, as this could cause further stress.
Remember that if your hamster is immobile and unresponsive for an extended period, it's crucial to seek professional help from a veterinarian to ensure prompt diagnosis and treatment.
