Help aid the relief of hairballs and mild constipation with Aristopets Laxative for Cats. Its tasty flavour and easy application make dealing with the unpleasantness of hairballs a breeze. Given the highly palatable formula, most cats will accept Cat Laxative readily. But for more fussy felines, you may place a small amount on their paw, encouraging them to lick their paw and ingest the laxative. A 2-3cm squeeze is adequate for an average sized, 4kg cat.
