Cats cannot eat the leaves of peony flowers. After eating, they may cause poisoning, such as diarrhea and vomiting. Because the peony flower belongs to the Ranunculaceae family, most of these plants are poisonous. The peony leaves are also part of the peony flower, so they cannot be eaten. Although it is not very toxic, it cannot be eaten by mistake.

If the cat does have a preference for eating plants, you can:

1. Plant some cat grass to meet the cat’s occasional grass-eating habit.

2. In addition to feeding normal cat food, cats can also be given improved meals, such as special canned cat food and chicken strips, so that they can get added protein.

3. Walk the cat on a leash appropriately outdoors, which can increase the cat's activity, avoid the formation of stones, eliminate the discomfort caused by stones to the cat, and also make the cat happy.
