I would agree with some of that,but if *they* would much rather be in than out,why do they go out? Our cat stays right by the door at all times,and after she runs in and eats she's back out. Keeping her in is near impossible,as she will simply wait until someone is coming in or out. I don't think for one minute she would rather be in....I feel like it's about quality of life,and I was definitely upset when she was gone and I'm pretty sure taking a Honda to the leg was not good for her either,but if going out is what she loves to do so much,than eventually we might all have to pay the price...and I let her go. Only now I'm much more cautious about looking for her before moving my vehicle.
