Two kittens

Almost two weeks ago, while leaving shul on Saturday night, I noticed two kittens in an alley huddled together and shivering. We couldn't leave them out there to freeze, so Stacy and I brought them home.
They were scared, cold and hungry little kittens. You'd put out food and they'd scarf it down as fast as possible, then try to hide. Fortunately, by now they've been de-flea'd, de-wormed, (more or less) litterbox-trained, and most certainly fed. So now they're friendlier and much more active.
Now the trouble is keeping them off our furniture, etc. And, after seeing some of their antics, I'm convinced that whoever coined the phrase "curiosity killed the cat" probably had a cat.
Oh, and it seems like we're keeping the little critters. The one with black in its fur is called Gravity and the other is Widget.
