CATDOLL : When changing cat litter, do I have to throw away all the old one?

If there is only a small amount of excrement left in the cat litter box and the cat litter as a whole remains dry and clean, you do not have to pour it all out. Just clean out the contaminated cat litter and excrement, and then add an appropriate amount of new cat litter.

However, if most of the cat litter in the litter box is already contaminated, or the litter box has not been thoroughly cleaned for a long time, it is recommended to pour out all the old cat litter and thoroughly clean and disinfect the litter box to ensure the health of the cat and the hygiene of the living environment.
