It is true that purebred cats can't make money at a high market price, but purebred cats have poor resistance and are prone to illness. They can't do it without professional breeding methods. If you want to keep a cat, you should also refer to the market. Some varieties are out of fashion, or there are too many people. Even if they are bred, they are difficult to sell. If they stay longer, it will increase the cost. Choose the best-selling colors and varieties in the market. For example, gold will be very hot this year, and the price with good appearance will be very high. Choose a big city, and there will be more cats in tall buildings! There are more dogs in the suburbs! Cats are generally in estrus in spring and autumn, and have at most two babies a year. Too many babies will harm your health and your life will be short. It is not suitable for childbearing after the age of three. The survival rate of kittens is low. You can find someone to adopt them at a low price after retirement. Only by choosing a good cat breed can beautiful offspring be born. The variety is not pure, the products are different, and it is difficult to sell! Moreover, kittens are prone to illness and have a low survival rate. Be sure to learn the nursing knowledge of kittens in advance, understand the common diseases of kittens, and make full preparations. Don't eat cat food too badly. If the cat is in poor health, it is easy to have dystocia or malnutrition without milk! The daily cost of buying a cat and canned cat food is already very high, so we must start with selling high-priced varieties, otherwise it is easy to lose money! And you don't need to raise too much, otherwise the daily expenses will be too high. A male cat and two or three female cats are the best in the kitten house!
