First, conduct a visual check on your pet mice first thing in the morning and right before you turn out the lights. It is not necessary to handle your mice when you do this; all you need to lift is the lid of the cage and ensure that each mouse is breathing properly, has an upright posture, clear eyes, and a glossy coat.

Once a week, handle each mouse. Gently use your fingers to detect any possible lumps or bumps on its skin. It should be neither too skinny nor too fat. If possible, do this during cage cleanup to disturb your mice as infrequently as possible.

Check your mice’s weight on a regular basis. Better yet, visit a pet clinic 4S Ranch for professional assessment and a thorough check-up. Have a look.

Lastly, always be very gentle and patient when handling your mice.
