1. Laws against animal abuse:
All states in the United States have laws protecting animals from abuse. These laws include definitions of what is considered abuse (such as neglect, beatings, failure to provide food and water, etc.).
Violation of these laws can lead to criminal penalties, fines and even imprisonment.

2. Public health laws:
Street animals can carry diseases, so there are laws aimed at protecting public health. For example, municipalities may run programs to vaccinate stray animals or catch them and check their health.
These laws may also include regulations regarding castration and sterilization to prevent their uncontrolled breeding.

3. Sterilization and castration laws:
Spaying and neutering programs are part of the effort to prevent the culture of street animals. Many countries offer laws that encourage spaying and neutering through subsidies or financial assistance.
These programs not only help reduce the population of street animals, but also improve their overall health.

4. Seizure and release laws:
Many cities have enforcement bodies (such as the health department or animal protection authority) whose job it is to catch street animals in cases where they endanger the public or themselves.
After capture, the animals are often taken to shelters, where they receive medical treatment, vaccinations and opportunities for adoption.

5. Eating rules:
In some places there is a ban on the uncontrolled feeding of street animals, in order to prevent health problems and to prevent uncontrolled breeding.
Sometimes, a license is needed to feed street animals, and the law may require that the feeding be organized and controlled.

6. Enforcement laws:
Many of the cases where it is necessary to treat street animals are handled by public bodies or associations. Laws dictate how these animals are treated, and in most cases they have the authority to seize animals and perform treatment operations.
There are also laws that guide these bodies on how to behave in the case of injured or sick animals.

7. Liability for animals:
Pet owners are responsible for keeping their animals within their premises and making sure they don't roam the street. These laws may include fines for pet owners who keep untethered or unattended animals.

8. Animal welfare laws:
Many of the animal welfare laws are designed to improve the quality of life of street animals. This includes laws dictating the conditions under which animals must live, such as access to food, water and shelter.
There are laws that guide animal shelters regarding the conditions of conduct, how to care for animals, and offering adoption programs.

9. Local plans:
In many cities there are community programs aimed at managing the animal population. These programs include public education, adoption registration days, and spay and neuter programs.
Many associations work in cooperation with the authorities to promote animal welfare and prevent street animal problems.

10. Changing rules:
It is important to remember that these laws vary not only from country to country but also between different cities in the same country. Therefore, it is always a good idea to check the specific laws in the place you are interested in.
