Design and implementation of stray animal communication information platform based on Java + Springboot + LayUI

​

Introduction:

Walking around the campus, I would occasionally see a few cats, or dangling on the path, or lying curled up on the edge of the flower bed, just like homeless poor children, really sad! In fact, they are just some stray pets abandoned by people. Stray pets refer to ownerless pets that live in the wild for a long time. Unlike feral cats (dogs), stray pets refer to those that have been adopted by people before being abandoned for some reason. Some reasons, may be because of the owner’s housewarming, may not be able to keep up with the economy, may also be just the owner does not like, abandoned. As a matter of fact, there are many, many other poor dogs and cats who suffer the same fate as them in all parts of the country. Luckily for the cats on campus, some kind classmates often give them food to keep them from starving to death. In addition, those stray pets not only lost their warm homes, lost the care of their owners, even the basic food has become a problem.

Since the domestication of cats and dogs and other small animals, as human partners, they also have their own reason and emotion, we should give full respect and care. However, with the development of social economy, the number of small animals such as cats and dogs is increasing, and some people abandon and abandon stray animals, more and more. This requires social institutions or warm-hearted people to care for and rescue these stray animals. Under the background of social networking, promoting the harmonious coexistence of human and animals accords with the characteristics of The Times. The development of a voluntary rescue website for stray animals can provide a platform for some organizations and caring people, so that small pets can better find their owners and make their survival easier. At the same time, it can also provide transfer services for some owners who do not want to keep pets. Raise people’s awareness of animal protection, animals are also a member of nature people should protect them, advocate the social atmosphere of caring for animals, promote people and animals to get along more harmoniously. Therefore, the research of this topic is in line with the current situation of The Times, and will take a small step to create a good social environment for human and natural animal life to coexist harmoniously.
