Syrian hamsters are commonly kept as children's pets but suffer widely from inadequate cage size, social housing attempts, and insufficient burrowing opportunities.
Syrian hamsters in small cages cannot run the 5-8 km they cover nightly in the wild. Exercise wheels must be large enough for natural gait without back arching (minimum 28 cm diameter). Deep substrate for burrowing is essential — wild hamsters dig burrows over a metre deep. Daytime disturbance causes stress as these animals are adapted for night activity. Attempting to house Syrian hamsters together causes severe fighting injuries. Most commercially sold hamster setups fail to meet basic welfare requirements.
