You did a really good thing, Mike. I love dogs very much, but I will have to admit that cats, generally, hold an extra-special place in my heart. It was a very good deed to save Mason, and it looks like he's giving you the full cat-love treatment in return.
That's too bad about the declawing; living indoor/outdoor is such a better lifestyle for a cat than indoor only. Yes, more dangerous, but if cats could conceptualize and talk I'd bet they'd say it's worth it: trees, birds, field mice, meeting other cats, and space, space, space. Like you said--the bastards. Declawing is mutilation, pure and simple. I'd rather accept some ripped furniture along with my cat than declaw him or her. I'd like to ask people who declaw their cats if they'd cut off their toddlers' hands so they don't break anything. If you'd accept your kid breaking some lamps or knickknacks, then you ought to be willing to accept your cat creating some bare patches on your carpet. I mean, bg freaking deal---is it worth mutilating your pet and forever cutting him off from an outside life?
Sorry, I really just wanted to compliment you on your good deed and then went off on a declawing tangent.
