  • Recognize healthy behaviors
  • Always try to keep your hamster in a clean and stressless environment with clean water and food.
  • Be observant with your hamster when you play with it.
  • When it gets sick, isolate it from other pets. Clean the area and your hands as some disease may be transferrable to humans.
  • Find a suitable vet and take it there. Follow their instructions.
