Can cats and canines interbreed?

Mules are miscellaneous families of horses and donkeys, but both horses and donkeys belong to the equine family; lions and tigers (or tiger beasts) are crossed by lions and tigers, both of which also belong to the cat family. So can cats and canines interbreed? According to biological data, in terms of biological genetic characteristics, it is impossible for animals with distant consanguinity to cross, and even if artificial insemination is adopted, the possibility of producing offspring is equal to zero. At present, the different kinds of animals that can successfully interbreed should be at least animals of the same family, such as horses and donkeys, dogs and foxes. The habit that different animals are difficult to interbreed helps to maintain the stability of animal genetic traits. In addition to the rejection ability of the chromosome itself, different animals have different ways of courtship, which is difficult to be understood and accepted by heterogeneous animals, and avoids the occurrence of hybridization. Therefore, cats and dogs cannot be crossed.

Attachment: the cat family is not only the strongest carnivorous family in the carnivorous order, but also the strongest family in land carnivores.

Lives on all continents except Antarctica. Most cats are good at concealment, hunting in ambushes, often spotted, and can blend in with the environment.

Nowadays, most cats are caught and used to make high-end fashion because of these beautiful spots, and other reasons such as habitat destruction pose a serious threat to cats. As important predators, especially the top carnivores, the decrease of the number of cats has a great impact on the ecological environment.

The first kind of cat appeared in the Oligocene about 30 million years ago, and the more familiar connection between domestic cats and humans began thousands of years ago.

Cats, whether domesticated or wild, have attracted humans for thousands of years. During this period, the relationship between humans and these animals has also undergone extensive changes. People once valued them as hunters, worshiped as gods and sacrificed as demons, but in any case, they survived and were still infatuated.

They are often used as symbols of beauty, elegance, mystery and power, and have become a favorite theme for many artists and writers.

There are three categories: large cats and small cats, which fall into one category because of the unique size of cheetahs.

Annex 2: canines belong to vertebrates, mammals and carnivores, all of which are terrestrial, and only a few species occasionally climb trees. There are 34 species of canines in the world, which are divided into 12 genera. Canines include dogs, wolves, jackals, foxes and so on. Canine is one of the most successful carnivorous mammals on earth. The canine family includes about 37 species of living wolves, wolves, foxes and other wild animals and domestic dogs. They are all carnivores, and their bodies have evolved into a form that is particularly suitable for hunting life.

There are many different opinions on the genetic relationship among canine members and the division of subfamilies, and these opinions are even very different. In terms of body size and habits, canines can be divided into dogs that are larger and have strong carnivorous habits, which can prey on larger prey, and foxes that are smaller, have slightly miscellaneous feeding habits, and mainly prey on small animals.

Most species are active day and night, a few species are dusk, only raccoon dogs have hibernating habits. Carnivorous and occasionally plant-based foods. The fecundity is strong, most of them are 1 child a year, and each fetus gives birth to 2-13 litters. Most species of fur are precious, some species feed on rats and play an important role in ecological balance, while others damage livestock and poultry and cause serious losses to animal husbandry. Wolves and foxes are carriers of many kinds of pathogens and do some harm to human beings.
