Start a kitten with a modest, even layer of familiar unscented litter—deep enough to dig and cover without sinking. Adjust gradually by watching how the kitten uses the box.

The short answer
Kittens need a consistent, comfortable substrate they can investigate and cover without sinking deeply.
Why it may happen
Individual preferences vary, while sudden changes in texture, scent or depth can lead to hesitation.
Read the whole situation
One behaviour rarely has one guaranteed meaning. Compare it with your cat’s age, health, posture, appetite, litter habits, environment and usual pattern before drawing a conclusion.
What to do now
Begin with a modest even layer of unscented litter, observe digging and keep the box easy to enter and clean.
What not to do
Avoid punishment, forced handling and sudden large changes. They can add fear while hiding the information that would help you understand the original cause.
When to contact a veterinarian
Straining, crying, diarrhoea, constipation or repeated accidents can have a medical cause and need veterinary assessment.
Keep a useful record
Write down when it started, how often it happens and what immediately precedes and follows it. Photos, weights or short videos can make a veterinary or behaviour consultation more productive.
Let the kitten show you the preference
Use a large stable low-entry tray and keep litter type, scent and depth consistent at first. If the kitten perches, digs to the base or avoids stepping inside, test one small depth change in a second tray rather than replacing every option at once.

Keep setup separate from medical signs
Scoop frequently and keep the tray on a quiet non-slip route. Accidents are not spite. Straining, crying, repeated visits, diarrhoea, constipation, blood or reduced urine needs veterinary assessment instead of another litter experiment.

Questions cat people ask
How deep should litter be for a kitten?+
About 3–5 cm suits many kittens, but size, material and individual preference matter. The kitten should stand securely and cover waste comfortably.
Why does my kitten dig to the bottom?+
Some kittens prefer a different depth or texture, while others simply dig enthusiastically. Adjust one factor at a time and confirm the box is roomy and clean.
