Each pig was covered in a fine dust of pepper and salt granules and was grooming furiously , their tiny eyes glued shut as a result of nature 's cruel decision to deprive them of the ability to cry the salt out . Poor wee feckers . I went to grab a toothbrush to groom the stuff out , and let a horribly evil thought cross my mind .

Question: Why was the narrator going to clean the   pis ?
Answer: None of the above choices .He had a pet pig with its own toothbrush that he used to brush its teeth .Because he is a farmer and the pigs belong to him .He worked in a slaughterhouse and they had to be groomed first .
