Municipal Corporation of Delhi — complaint about street cats my building

I am riya from sai aprtments sector-13. I have complaints regarding the street cats living inside our building which is causing a great threat to children living in our building. There is a family who feed 7/8 cats inside the building which not only creates a mess and a bad environment but also gives no path to all the people living in the building to cross the stairs down/up.
I request you to please take an action as soon as possible.
I hereby provide some details to further contact me
