4. Common sense of cats

First of all, if possible, it's best to go to the cat owner's house to choose. First, look at the physical condition of the mother cat and the cat in the same nest, because the physical condition of the parents' cat will directly affect the physical condition of the next generation of kittens.

We should choose from the offspring with excellent varieties, strong physique and beautiful figure. Let's take a look at the growth of kittens. Are they lively, cute, smart, strong, with a good appetite and shiny fur?

Don't choose the smallest cat in the nest (that is, weak cat), because it is weak, slow-growing, prone to illness and difficult to feed. Second, check whether the cat is healthy.

The logo of a healthy cat is: 1. Eyes bright, no tears, no secretions, no inflammation; 2. The ears are clean and upright, with little or no earwax and no other foreign bodies; 3. The mouth should be clean and dry, without saliva or food, and the teeth should be solid, pink and ulcer-free; 4. The coat is smooth, the skin is soft, there are no bald spots and lumps, and the skin is not red; 5.*** and external genitalia should be clean, no secretions, and nearby hair should not be stained with feces and dirt; 6. The body muscles are solid and developed, and there is no rash. Don't choose a kitten with a runny nose and tears.

Healthy cats are sensitive to their owners' calls or other sounds in a quiet state, and their ears will swing back and forth after hearing the sounds. Sick cats or deaf cats don't respond to sounds.

When you win a kitten, you should try calling it to see if the cat responds. If the kitten is easily frightened or grinning, it is necessary to carefully observe whether it is unwell, afraid of its new owner or does not adapt to the new environment.

Third, learn to tell the age of a cat. Generally speaking, cats begin to grow deciduous teeth in the second to third week after birth, and begin to change their teeth in the second to third month. By the sixth month, all the permanent front teeth will be lined up.

1 year later, the lower incisors began to wear, the canine teeth began to wear after 5 years, the lower incisors rounded after 7 years, and the upper incisors rounded after 10 years. The age of a cat can also be roughly distinguished according to the growth of hair and the color change of hair.

After the cat is born for 6 months, it will grow new hair to indicate adulthood; 1967, I was middle-aged. At this time, a white beard grew out of my mouth. In old age, white hair grows on the head and back. The six points for attention in raising cats are: 1. The cat's food plate should be fixed and can't be changed casually.

Cats are very sensitive to the change of food plates, and sometimes refuse to eat because of the change of food plates. Keep the food plates clean.

Newspaper or plastic paper can be placed under the food tray to prevent the noise caused by the sliding of the food tray, and it is also easy to clean. Every time the cat eats leftover food, throw it away or put it away, and mix it with fresh food and cook it before feeding it next time.

2. Feed regularly. Once the biological clock of a cat's "rice" is formed, it is relatively fixed and should not be changed at will.

The place where grazing cats eat should be fixed. Cats don't like eating in noisy and bright places. If guests come to visit, don't let them see your cat while it is eating. The appearance of strangers will greatly reduce the appetite of cats. Cats have the bad habit of grabbing food with claws or taking food from food plates.

Once this phenomenon is found, it should be corrected immediately. Cats like to eat hot food.

Cold food not only affects the appetite of cats, but also easily causes digestive dysfunction. Under normal circumstances, the temperature of food should be 30~40 degrees, and the food taken out of the refrigerator should be heated before feeding.

Although cats don't drink much water, they must have enough clean water. The drinking water for cats must be clean water, which should be changed every day.

The drinking basin can be placed on one side of the food tray, so that cats can drink freely when they are thirsty. 6. Observe the cat's appetite at any time.

There are many reasons that affect the appetite of cats, including feed, environment and diseases. If the cat's food is single and stale, or the smell, concentration and taste of the food are not appetizing, the cat will refuse to eat.

If the cat food is mixed with more patterns and better palatability, the cat can always maintain a high appetite. In addition, the taste of food should not be too talkative or too salty.

Cats like sweets or foods with fishy smell. In addition, strong light, noise, the presence of strangers or the interference of other animals will affect the appetite of cats.

If these two factors are improved, the cat's appetite still hasn't improved. It may be that the cat is ill. Please seek veterinary treatment in time. Four points for attention in cat training 1. Grasp the age and opportunity of training: the training of cats should start from the age of 2~3 months, when it is easier to receive training and lay the foundation for future improvement.

If it is an adult cat, it is more difficult to train. The best time to train cats is before feeding, because hungry cats are willing to be close to people and obedient, and the attraction of food to cats makes the training easy to succeed.

2. Kind attitude, various combinations: cats are stubborn, self-respecting and unwilling to be pushed around. Therefore, in training, we should combine all kinds of * * * and means organically, and be kind, just like playing with cats. Even if we do something wrong, don't reprimand or punish too much, lest the cat hate training and affect the completion of the whole training plan.

Step by step, don't be too hasty: you can only teach one movement at a time, and you must never do several trainings at the same time. It is difficult for a cat to learn many actions at once. If you don't do it well all the time, it will also make the cat lose confidence, cause the cat's boredom, and bring difficulties to future training.

Each training time should not be too long, no more than 10 minutes, but you can train several times a day. 4. The training environment should be quiet: several people can't train at the same time, so as not to distract the cat.

Training movements should not be too sudden or loud, because cats are very sensitive to loud noises or sudden movements, so as not to scare the cats away and hide, instead of being trained. The average life span of cats is 12 years old, and the longest-lived cat recorded in literature lives to 30 years old; Cats generally reach sexual maturity in 7-8 months, and their sexual cycle is 15-28 days. The suitable breeding age for cats is 10- 18 months old, 60-68 days pregnant and 60 days nursing. The normal body temperature of cats is 39℃, and the general range is 38-39.5℃ (rectal temperature). The heartbeat frequency is 130- 140 beats/min for young cats and 100- 120 beats/min for adult cats. Breathing frequency is 20-30 times/minute; Total blood volume accounts for 6.2% of body weight, red blood cells are 8 million /m3 (normal range is 6.5 million ~ 9.5 million /m3), and white blood cells 1.6 million /m3.
