Although I could argue that just by being vegan, I'm doing a good deed every day! ;)
Anyway, this morning I spotted the BIGGEST spider I've ever seen in my life. I was both fascinated and repulsed as I saw her/him sitting cozily right by my cat's water bowl, but I knew he/she couldn't stay. Now I have to explain that I used to have this enormous spider phobia when I was younger (and I think there may be something to the theory that you attract what you fear as during the reign of this phobia I once spat out a spider that had been in my coffee, was bitten by one, and encountered countless spiders in beds, bathtubs and basements!), so am not overly fond of these creatures although I no longer fear them. Or attract them, snort. So before Kitty Kazoo could come along and be equally fascinated by the water bowl visitor, I quickly grabbed a plastic container, scooped up Ms. or Mr. Spider, and released the captive outside. And not harming any living being if you don't have to is definitely the right thing to do, but I've already released a cricket and a centipede (a former cat used to eat them -- eeeeww), so I sure seem to live in a buggy place right now!
