I've heard from a few. Now, as it turns out, I am not just a dog nut, but also a cat freak.
This is a shot of my girls -- Fox and Socks (in that order), in their favourite habitat, under my bed. (Please note rare, no-dustball shot!)
The girls are twins, of course, but definitely not identical. Fox has a pointy foxy face (naturally) and is quite a bit tinier than her often cross-eyed, larger sister.
They are also, unlike Seamus and Silas, terribly camera-shy, so I'll make it a mission to try to get a couple of better shots of them soon.
In the meantime, for all you cat lovers (or lovers of Engineers, for that matter), may I suggest this small entertainment:
