For the health and comfort of our lovely friends, pay attention to this...

It is recommended to replace plastic cat litter boxes every 1-2 years.

  Plastic cat litter boxes begin to wear out with the cat scratching. In addition, cat urine is acidic and accelerates toilet wear. In addition, cat urine penetrates the scratches caused by scratching more and the toilet continues to emit odor no matter how clean it is cleaned. While changing the sand and cleaning the toilet, you can check the floor of the toilet to see if it is time to change. If there is an odor coming from the cat toilet despite all the cleaning you have done, it means it's time to change the toilet.
