i have all my stuff in a shoe box: yeast nutrients, campden tablets, metabisulfate, bottle washers, etc. Unfortunately, I thought I could leave the shoe box on the dining room table. Three times now, my cat has gotten into my box, rummaged around, and dug out the yeast nutrients. She bites thru the bag and slobbers on it for a while, sometimes spreading granules of the stuff all over the table. I've lost a bag of Fermax and two bags of Fermaid K this way. Finally moved the box into a closet before she gets a hankering for DAP. I don't know whether she likes the yeast hulls or some other chemical. But I hope it doesn't hurt her. Anybody else have experience with cats eating their nutrients? LOL
