I live in a third floor apartment. This morning there was a cat on my balcony. When we came near to the door, she ran, leaving behind two kittens. So now my mother and I are trying to figure out what to do with these two tiny kittens. We're not cat people.
One's eyes weren't even open. The other was wandering around and we were afraid he would fall off the edge. And they were shivering. So we put them in a box with a towel and tried putting them on the ground, hoping the mother would come to them down there. We went back up and examined the balcony, deciding they probably had been staying under the tarp covering our bbq pit. I lifted the cover a little bit to find another kitten. At first I thought it was dead and it freaked me out. He fell out of the tarp as I lifted it, but he was alive and fine.
We brought the other box of kittens back upstairs, placed it under the tarp and left for the day. When we came home the mother was in the box with her kittens. We put some food and water out for her. I don't know how old the kittens are or how long they've been there. I don't know if the mother gave birth on our porch or if she carried her kittens up there for some reason. But for now we have some balcony pets.
