Funny enough C&K the brand of shavings is called Pestell's, hows that for a little humour. All I know is that they switch back and forth from a different kind, and it depends on what location I buy it from as well. I'll be right back as I check the second bag they sell. Alright the second one is Pet's Pal, I try to tend to stick to these kind, because they are made in Canada, and they are a bit less expensive, not to mention I don't like getting anything from walmart, because it's mixed with cedar, and they don't tell you that (but you sure can smell it in there). As for the hay, the gentlemem I bought it from kept it in a hay loft above his barn, if that makes a difference, it was away from the elements. I can try to keep as much as possible inside, but my house is almost a completely finished house, and my parents are not keep on having even the shavings inside. I bought two bails of hay this time, and I'm glad I did, the first bale the hay was kinda thicker, and the pigs spent most of the time rummaging through it to pick out the grassy pieces, so I switched to the other bale witch is mostly the grassy type.
In case it makes a difference, there isn't any vehicles in my garage ever, it's just a extension to my house, where more toys are kept, nothing is ever idling in there though, and the bales of hay are kept in the corner with filing cabnets, in industrial size clear plastic bags.
As for the worming, it had to be done sooner or later, I had put off doing it myself, cause I didn't trust the syringes, or my measuring. I'm heading off my work to pick up paychecks, which is right beside Zellers, if you reply sometime soon with a posisitive on the containers, I'll pick a few up. I'm not quite sure where to get paper bags though.
