JFS explains cruelty toward animals disqualifies people from the companionship of the Holy Spirit.
Joseph F. Smith, "Editorial Thoughts: Kindness to Animals," Juvenile Instructor 47, no. 2 (February 1912): 79
. . . he who treats in a brutal manner a poor, dumb animal at that moment disqualifies himself for the companionship of the Holy Spirit; for the Lord will not sanction an unrighteous act and it is an unrighteous thing to treat any creature cruelly. If the treatment be given in anger the result is the same, for anger itself is displeasing to the Lord, and the ill-treatment of the animal under such conditions, gives him double displeasure.
