Katalax is a palatable & easy to administer blend of top-grade, soft white paraffin, cod liver oil & malt extract used to promote the elimination of hairballs or to relieve mild constipation. Directions: Administer one inch of paste from the tube, once or twice daily. For kittens, half this amount. For fussy cats, smear a small amount of paste on their paw, allowing the cat to lick it off & become accustomed to the taste.
