Dietary considerations for cats in winter:
1. Increase the proportion of meat in their diet. In winter, owners need to adjust their cats' diets, as cats tend to eat more to store energy for the colder months. Owners should appropriately increase the proportion of meat in their cats' diets. For example, if they previously only ate kibble, owners can now add some high-quality wet food pouches, canned food, and boiled chicken breast. This will increase their cats' nutrition, maintain their metabolic rate, and also provide a higher protein intake.
2. Increase the vitamin ratio. Vitamins are very important for cats as they aid digestion, boost immunity, reduce illness, and promote healthier skin and fur. You can feed your cat some boiled animal liver, such as chicken or pork liver, every two weeks. Most cats will accept cooked eggs, which can also be given in small amounts. 
3. Supplement calcium. As winter approaches, owners should pay close attention to any unusual symptoms in their cats, such as leg weakness. If this occurs, consult a veterinarian for targeted calcium supplementation to prevent calcium deficiency.
4. Replenish fluids. Experts recommend that cats consume 2-3 times their daily dry matter intake of water. This means that if a cat eats 100g of cat food daily, it should drink around 200ml of water. This is mainly to prevent dehydration, which can lead to loss of appetite and indigestion.
5. Feed them at regular times and in measured amounts. In the cold winter, cats often have a greater appetite. Owners should control their food intake, preventing them from eating and sleeping in the same time, and avoiding overeating. Maintaining regular, measured meals, and engaging in appropriate interaction with your cat to increase its activity level are the best ways to ensure its healthy growth.
6. Other: In terms of food, you can provide more high-quality protein, choose some good cat food, and you can also add some chicken breast and beef.
