- Cleaning Difficulty: Cleaning non-clumping litter can be more cumbersome. Since it does not form solid clumps, waste can become mixed with the litter, making it challenging to remove soiled material without replacing a significant amount of clean litter.
- Tracking Issues: Non-clumping litters may lead to more tracking outside the litter box. Due to their larger granules or texture, they can adhere to a cat’s paws more easily and be scattered around the home, creating additional clean-up work for pet owners.
- Absorption Limitations: Non-clumping litters generally have a limited absorption capacity. This can result in the litter becoming saturated more quickly, necessitating more frequent changes and potentially leading to a less hygienic environment for the cat.
- Texture Preferences: Some cats may prefer the feel of clumping litter. If a cat is accustomed to clumping litter, they may be less willing to use a non-clumping alternative, which could lead to litter box avoidance and related behavioral issues.

Monitor Behavior: Keeping an eye on your cat’s behavior is essential to ensure they are adapting well. If they show signs of distress, such as avoidance or accidents outside the box, you may need to revert to the old litter temporarily and try again later.
Choose the Right Litter: Selecting the best cat litter for Litter Robot is paramount; look for options that are low in dust and have good clumping properties. A litter that resembles the texture and smell of the previous one can make the transition smoother for your cat.
