Step-by-step explanation:
Rat cages should be changed regularly to maintain the health and well-being of the rats. The frequency of cage changes depends on various factors such as the number of rats in the cage, the size of the cage, and the cleanliness of the environment. As a general guideline, it is recommended to clean the cage at least once a week.
During cage cleaning, all bedding should be replaced, and the cage should be thoroughly cleaned and disinfected to prevent the build-up of bacteria and odors. Rats are sensitive animals, and a clean and comfortable living environment is essential for their health. Regular cage maintenance also helps prevent the spread of diseases and improves the overall hygiene of the rats' living space.
Remember to also provide fresh food and water daily to ensure the rats' nutritional needs are met. Keep an eye on any signs of illness or distress in the rats and consult a veterinarian if necessary.
