Cats & Kittens, when licking their fur, can accidentally ingest it, which may then accumulate in their stomachs & form what is known as a hairball. Signs of hairball are constipation, gagging, coughing & vomiting. Our Defurr-um paste aids in lubricating the digestive tract helping to expel potential blockages. Defurr-um paste is highly palatable & is easily administered either by placing it directly onto your cats paw or letting them lick it from your finger.
