Drafts and Pigs

They should be fine as long as the fan isn't blowing directly on the cage. I don't have air either. My pigs really like it when I put frozen water bottles in their cage. I put them wrapped in a thin kitchen towel in their hiddey houses, so they houses are cooled off. I also fill a gallon sized ziplock bag half way with water, lay it flat in the freezer and make them a frozen water bed and wrap that with a towel. They love to lay on those. I also have little marble slates in there to lay on. I swear my pigs keep cooler than I do.

I've heard bricks work to keep them cool. Also you can get a soda bottle(12 or 20 oz size) fill with water and freeze. That way you can give them something cold to lay with and when it turns to water, refreeze it again. That trick works with bunnies too.
