I know piggies want to chew all the time.He might have been looking for something to chew on. I wouldn't think he would like cat food since pigs are vegetarian. You might want to get some bottled water for your pigs. Hard water can cause white, brown or red stains. It depends on which minerals it has what color the stains will be. I think lime and Calcium are white. Growing up we had to get a water softener because we had a lethal amount of Calcium. When the man did the test instead of getting little white flakes in the test tube of water he got a huge chunk. We got a culligan system then we bought the "salt" or water softener at the local home improvement store, it may have been lowe's. It was cheaper to buy it our selves than to get on one of the delivery plans.
