There is a lady in the building who leaves food and a box for sleeping to a homeless cat.
He come whenever he feels like to eat there and sleep.
People already know him and when they meet him they start talking to the cat and open the door for him.
Once I met this lady and told her how much I appreciate what she does. She said: “I do what I can to help him.”
Would be wonderful if we all can do what we could to help homeless pets.
If you cannot help, at least don’t hurt them.
