Bidalasana or Marjariasana, both meaning Cat Pose in Sanskrit, is a kneeling asana in modern yoga as exercise. A variant with one leg held up is Vyaghrasana, Tiger Pose; a similar variant with one leg held straight out is Chakravakasana, Sunbird Pose. A variant with the back lowered is Bitilasana, Cow Pose; this is often used as the counter-posture, and a widely used exercise is to alternate between Cat and Cow Poses repeatedly.
