The short answer
True lilies and daylilies can cause fatal kidney injury in cats after very small exposures.
Why it may happen
A cat may swallow pollen while grooming or drink contaminated vase water without visibly chewing the plant.
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
Keep lilies completely out of cat homes and contact a veterinarian or poison service immediately after possible exposure.
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
Do not wait for symptoms and do not try home remedies unless a veterinary professional directs you.
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.
What to check first
Do not wait for symptoms after possible contact. A cat can ingest pollen while grooming, and early vomiting or lethargy may be mild before serious kidney injury develops.

What to do next
Remove the cat from the area, prevent grooming and call an emergency veterinarian or animal poison service immediately. Bring the plant name or a photo without delaying departure. Any suspected lily exposure is an emergency even when the cat looks normal; do not induce vomiting unless a professional directs it.
