Spencer's dad-
in defense of the folks that belong to the repeatedly lost declawed kitty-

1) Some cats just get out, no matter how much you try to keep them in. My mom cat was a pregnant homeless street cat when I adopted her. She had a taste of the outdoors and frequently escapes. Now her boy has caught on - he's nearly twenty pounds and when he pushes past your legs out that door it's very hard to stop him. I consider my cats to be indoor cats, and endeavor to keep them indoors, but it's a futile effort sometimes, and I then have to resort to prayer.

2) I do not put collars and tags on my cats because a stalking boyfriend once traced me through my cat's tag. Other people may have had similar experiences or fears, especially us women who live with no men in the house. Also, if a collar is loose enough to not choke the cat it's also loose enough to come off, frequently.

I do agree with you, however, just wanted to note that sometimes things are not as they seem.
