food
There are three main types of pre-packaged cat food sold on the market: canned meat, semi-moist food, and dry food. While these three types are convenient, they should only be part of a cat's diet, not its entire diet. Ideally, cats should be fed fresh food at least twice a week. This is because these commercially available foods cannot provide all the nutrients a cat needs if you intend for it to live a long and healthy life. Many of these foods reportedly meet the recommended protein content for cats (25%–30%). However, like humans, cats should also eat fresh food to obtain sufficient vitamins and minerals. Furthermore, feeding a cat only this type of food can be too monotonous, even if some cats can tolerate this. And nutritionally speaking, pre-packaged food is quite expensive. However, there may be times when you feel you must use pre-packaged food as your cat's sole diet. As long as you feed it this for a few weeks, rather than years, and provide plenty of water when feeding dry food, your cat shouldn't find it unbearable.

Daily care
Cat claws are tools cats use for catching mice, climbing, and self-defense. If you keep a cat for catching mice, you shouldn't trim its claws. However, if you keep a cat as a companion animal, you should trim its claws regularly to prevent it from scratching people, damaging clothes, furniture, floors, etc. Claw trimming should begin when the cat is young, about once a month. Specific methods are as follows:
Hold the Siamese cat in your arms, grasp one of its paws with your left hand, and gently squeeze with your thumb, index, and middle fingers to extend the claw. Then, use nail clippers in your right hand to carefully trim the transparent part at the tip of the claw, and then use the small file on the nail clippers to smooth the claw. Do not trim too much to avoid injuring the Siamese cat's paw. Repeat this process for the other claws.
Bathing a Siamese cat not only keeps it clean and beautiful, but it also removes some parasites from its body, promotes blood circulation and metabolism, and helps prevent disease and maintain health. It's best to cultivate the habit of bathing a cat from puppyhood; if you only start bathing a cat when it's an adult, it will be extremely reluctant.
Before taking a bath, prepare the necessary bathing supplies, such as a bathtub, towel, detergent, comb (preferably with one sparse end and one fine end), and brush.
When bathing a cat, the water temperature should not be too low or too high; it should be warm to the touch. The shampoo used should not be too harsh to avoid irritating the skin. Long-haired cats should have their fur combed before bathing to prevent tangles. Bathing should be done quickly, ideally finishing in a short time. After bathing, the fur should be dried immediately with a towel. A towel cannot completely dry the fur; a hairdryer can be used to completely dry the fur. When the temperature is low, it is best to cover the cat with a special towel or other warm clothing to prevent it from catching a cold.
Siamese cats have rough tongues with special barbed papillae, resembling a comb, which they frequently use to groom their fur. For areas they can't reach with their tongues, such as the head, shoulders, back, and neck, they use their paws. Even so, it's best to brush your cat once a day. Cats shed year-round, especially during the spring and autumn molting seasons. When they groom themselves, they ingest fur, which can form hairballs in their stomachs over time. If these hairballs cannot be vomited out or expelled through the intestines, they can become trapped in the stomach, causing blockages, affecting appetite, and even endangering their lives.
When grooming, brush not only with the grain but also against the grain. For Siamese cats, you can first wet the fur with water and then rub it to make the fur stand up, making it easier to brush. If the fur of a long-haired cat is tangled or matted, you can use your fingertips to separate them or use a wide-toothed comb to slowly and carefully brush it. If the fur is felted, you can use scissors to cut the felt pieces into thin strips along the direction of fur growth, and then comb them. If the felting is severe, you can cut off some of the fur to allow it to regrow.
A healthy Siamese cat has bright, clear eyes. When a Siamese cat is sick or in poor health, it often becomes sensitive to light and tear up. Some cat breeds are prone to blocked tear ducts, which can also cause excessive tearing. Excessive tearing in cats often results in eye discharge around the corners of the eyes near the nose; this can be gently wiped away with a cotton ball soaked in a 2% boric acid solution.
Ear care for Siamese cats primarily involves earwax removal. The method is as follows: Disinfect the external ear canal with a cotton ball soaked in 75% alcohol. Then, use a cotton swab dipped in olive oil or vegetable oil to soften the dried earwax. Once softened, carefully remove the earwax with tweezers, being careful not to break the ear canal lining to prevent infection and suppuration. If the cat's external ear canal becomes infected and suppurates, gently clean it with a cotton swab dipped in hydrogen peroxide, repeating until no pus remains on the swab. Then, use absorbent cotton to dry the ear canal. Repeating this process several times should heal the infection. If the cat has excessive earwax and is shaking its head or scratching its ears, consult a veterinarian immediately. 
kitten care and management
Kittens aged 2 to 5 months are in their growth period. During this rapid growth phase, kittens require a significant amount of calories. A kitten weighing 1 kilogram at 3-4 months needs 130-250 calories per day, increasing to 100 calories after six months, and reaching 80 calories for an adult cat. Nutritionally, cats are primarily carnivores, so they require a high amount of animal protein. Furthermore, insufficient calcium intake can lead to incomplete bone, teeth, and claw development; taurine deficiency can cause blindness or cardiovascular disease; and vitamin A deficiency can cause visual impairment or deteriorating skin conditions. These nutrients should be supplemented. Kittens require 40% more calcium during their developmental stage than adult cats.
Because kittens need a variety of nutrients for development, feeding them only cat meat will lead to malnutrition. However, giving them excessive vitamins can cause poisoning. In the past, many cat owners fed them leftovers, but at that time, cats could hunt animals outside to supplement their nutritional needs.
Nowadays, cats are mostly kept indoors, so cat owners need to pay special attention to their nutrition. If you don't have proper nutritional knowledge, it's best not to prepare food for your cat yourself. Feeding your cat commercially produced cat food is a good way to ensure their healthy growth. It is recommended that cat owners choose different foods according to the cat's life stage (juvenile stage, adult stage, gestation period, etc.).
Finally, it's worth noting that while kittens eat a lot during their developmental stages, they generally learn to control their food intake on their own. For kittens, it's perfectly fine to feed them several meals a day as long as they're willing to eat; there's no need to restrict their feeding frequency.
Elderly care
As cats enter their senior years, they experience hearing loss, and some may gradually lose their hearing altogether. Their fur becomes thin and dry, with significant hair loss. Their bodies weaken, muscles atrophy, and the fluid in their joints dries up, leading to inflammation and discomfort. The lenses of their eyes become cloudy, appearing slightly grayish-blue. The fur around their mouth, nose, and ears turns white or yellow. Regular grooming and improved living conditions are essential for senior cats. Joint pain is a common ailment in older pets; if they cannot exercise regularly, gently massage their muscles or move their limb joints while they rest.
