Answer the question about text:

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 .

Why was the narrator going to clean the pis ?
Because he is a farmer and the pigs belong to him .
