Tips to keep your rats in good shape

  • Rats like a comfortable temperature ? 21 degrees will suit them nicely. Excessive cold or heat can cause or exacerbate respiratory problems
  • Your rats' cage should not be in a draught or direct sunlight.
  • Rats like high fat goddies, but ration junk food as an occasional treat.
  • Give your rats adequate exercise time out of the cage
  • Your rats' cage should not be in a draught or direct sunlight


  • Central heating can dry out a rat's lungs, making any respiratory problems flare up. Ditto fans and hot dry air if you have such a climate. If you see any sign of this, put water near their cage to increase the humidity.
  • Make sure your rats have something warm to bed into, as well as each other.
  • Wash the cage and bedding at least once a week. Urine releases ammonia which can make respiratory problems worse.
  • Do not use sawdust or wood chip to line the cage floor.
  • If one of your rats is proscribed medicine, make sure he or she finishes the course
