It all started a little over a week ago when we heard some meowing in the crawlspace. We thought a cat had gotten into it so I went outside and left the crawlspace door open overnight so the cat could get out. A few days later, we heard the meowing in the crawlspace again. Apparently, there was another way to get into the crawlspace. So today, I come home to find a cat sitting at my front door. It backed away as I approached the door and after I entered the house, it came back and lay down again. After having somebody chase it out of the yard twice, it came to my back door and started lying there. Now it is sleeping on a lawn chair on my back porch. Whenever somebody approaches the back door, it meows and scratches at the door as if it wants to be let in.
Whenever I approach it, it arches its back, holds its tail erect, and meows constantly. At first I thought this was a sign that it was afraid and ready to attack so I stayed away from it. After a while, I decided to see if it was really hostile. It let me pet it a couple of times and acted pretty friendly but in a cautions manner. It has a collar on it but there isn't anything on the collar.
I really don't want to have a cat but it won't leave. Its been a little over a week now and its still at my house. I tried calling the animal shelters but they are closed. What should I do?
I copied and pasted that from some other place I posted it.
