✓ A single exploratory lick differs from repeated swallowing, which needs veterinary attention.

✓ Contact a veterinarian promptly for repeated eating, a kitten consuming clumping litter, pale gums, vomiting or reduced stool.
A single exploratory lick differs from repeated swallowing, which needs veterinary attention. This guide separates the quick answer from the details that actually help at home, with no blame and no dramatic guessing.
Separate tasting from repeated eating
Record whether the cat briefly mouths a granule, repeatedly swallows litter or seeks it outside toileting. Note the litter material, clumping properties, amount, frequency and when the behaviour began. A video can help if captured without encouraging it.
Check for companion changes
Track appetite, weight, vomiting, stool, urine, energy, gum colour and any interest in fabric, plastic, string or soil. Pale gums, weakness or a broader pica pattern make prompt veterinary assessment especially important.
Reduce access safely
Contact the veterinary team about a temporary safer litter choice while preserving a usable toilet. Do not abruptly remove every tray or create toileting stress. Keep replacement material clean and monitor whether the cat still passes urine and stool.
Do not supplement or medicate blindly
Do not give iron, vitamins, mineral blocks, oil, laxatives or human medicine unless testing and veterinary advice support them. Excess supplements can be harmful and may delay diagnosis of the reason for the behaviour.
Recognise obstruction or illness
Seek urgent care for repeated vomiting, a swollen or painful abdomen, severe weakness, collapse, no stool, straining or suspected ingestion of a large amount. Repeated litter-box attempts with little or no urine is an emergency regardless of litter eating.

Patchy hair loss can follow itching, parasites, infection, allergy, pain or overgrooming. The pattern is useful evidence, but appearance alone cannot identify the cause.
