That is such an amazing event, with so many people making shelters for the kitties! I don't think my mom will let me put a rubbermaid tub in her yard (I'm living with her while my husband is in SK and I finish school), but I was considering asking my dad next time I see him to help me build a wooden one with "pretty" siding and such, so as it wouldn't offend my mother's aesthetic sensibilities, hahaha. We have in particular one big black male that I see around, but I've never been able to get close enough to see if he's neutered, and I'm not positive as to whether he's feral or if he gets put out by his owners to hunt (not too smart since we're right off the town's main road). There's also a cat that looks like it'd be really expensive, maybe a Himalayan or a Birman, but I don't see it as often and it's so skittish that I can't get within 20 yards. Feral or not, I figure shelter wouldn't hurt them.
