Katalax Paste is a highly palatable blend of white soft paraffin, cod liver oil, and malt extract that aids cats in the passing of hairballs and the softening of faeces. Most cats will readily accept Katalax in food or from the tube. However, for fussy cats, it may be applied directly to the paw and licked off. This supplement helps eliminate hairballs and furballs. Each tube contains 20g of paste.
