Methods to supplement calcium for cats:
1. Owners can feed cats special pet calcium tablets, which can help them supplement calcium and promote bone growth and development.
2. Feed cats more calcium-rich foods, such as goat milk powder, eggs, meat and other foods.
3. If the cat is in urgent need of calcium supplement, you can give the cat liquid calcium, which is easier to absorb.

Notes on calcium supplementation for cats:
1. Take your cat to bask in the sun more often. Exposure to the sun can help the cat supplement vitamin D, which is beneficial to the absorption of calcium.

2. Cats should be fed a variety of foods and a balanced diet to facilitate calcium absorption.
3. Do not blindly supplement calcium to cats. If the cat itself is not deficient in calcium, excess calcium may cause physical problems to the cat.
