I am working at an animal shelter, its a place where stray, lost, abandoned or surrendered animals, mostly dogs and cats  are kept and rehabilitated.
You should be commended for your work.  Many people ignore the plight of animals.
Yes we are a  no-kill shelter, but there are also shelters that euthanize sick animals, it they are not adopted fast enough
I think that is wonderful.  Do a lot of people come to adopt the animals you take in, or are they mostly old and sick animals?
No, a lot of young animals are brought in everyday, critics believe that animal shelter is the same as pound, but its not like that
I used to get a lot of mail solicitations from the North Shore Animal League requesting money.  Does your shelter rely on donations, or are you funded some other way?
We rely on donations,  in the United States there is no government-run organization that provides oversight
I think that there should be oversight.  The local petting zoo here had a famous groundhog named General Lee that predicted spring. They had to close it down due to animal neglect.
Petting zoo
A petting zoo (often called, or part of, a ""children's zoo"") features a combination of domesticated animals and some wild species that are docile enough to touch and feed. In addition to independent petting zoos, also called children's farms or petting farms, many general zoos contain a petting zoo. 
Most petting zoos are designed to provide only relatively placid, herbivorous domesticated animals, such as sheep, goats, pigs, rabbits, or ponies, to feed and interact physically

While no-kill shelters exist, it is sometimes policy to euthanize sick animals, and any animal that is not claimed quickly enough by a previous or new owner. In Europe, of 30 countries included in a survey, all but four (Czech Republic, Germany, Greece, and Italy) permitted the killing of healthy stray
