The base of your rats cage should be covered with shredded paper, avoid using sawdust/ wood shavings as this will annoy the rats eyes and nose. A separate space should be provided to sleep in with nesting material to keep them warm.
Rat Exercise & Play
Rats love to play, so make sure you have lots of toys to keep them occupied. Tunnels, ropes and a wheel are great toys to help ensure your Rats get enough exercise.
Choose an exercise wheel that will not catch your Rats tail, or hurt her feet.
