That's terrible, you should move to the country where there are no limits on how many cats you can have.
We had a similar situation last summer, when a kitten arrived in our carport - screaming for food. (He was screaming at our Great Pyranees dog, but that's beside the point.)
This kitten was so skinny, he looked like he wouldn't last another day without food.
Well, the kitten is now a huge cat. He has filled out quite nicely. He's still on the Humane Society list to be neutered, but luckily all of our females are spayed. His name is Charlie, btw.
Here in Mississippi, I am dreading each new day of November. It's hunting time again. A time when 3/4 of the population load up their dogs in their trucks and head out to hunt deer. They let the dogs go - and many do not return. This is when the 1/4 of us who do not hunt get to dodge lost dogs on the highway - and view the remains of others who have already been hit. It's just a matter of time, really.
Just yesterday - we saw 5 dogs on the highway. One our way to dinner - we saw a dog running along the road - and, just then a logging truck sped past us, coming our way. I noted to my husband that the dog would probably be dead when we returned.
It was in two pieces in the center the road, exactly where we had passed him. The good news is that he didn't know what happened.
Last year I picked up 4 separate dogs on the same highway - 3
we took the Humane Society (almost 30 miles away) and the 4th I took to a veterinarian because it had been hit by a car. It died.
I dread November.
