Vet Q & AWhat to do if my mouse isn't eating, drinking, or acting herself?
If she will allow, check her teeth to see if they are overgrown or maloccluded. Either may result in a decrease or loss of appetite. Soak her pellets in warm water or a bit of fruit juice to stimulate her appetite and make eating easier.
If she still does not eat or continues her aberrant behavior, have her physically examined by your veterinarian to diagnose illness or injury.
