I found two different dosage levels.

1 cc per two pounds of cat. Orally. Three days in a row.

or


Panacur 10% is a white oral suspension of fenbendazole as a ready to administer oral anthelmintic for domestic dogs, cats, puppies and kittens. 1 ml contains 100 mg active ingredient fenbendazole.
Dose of 1ml per 1kg bodyweight as a single dose for routine worming.

Google Panacure dosage for cats and read all the information.

At that strength, it would be the higher volume dose using the horse paste. It is only half as strong as the dog/cat medication you mentioned.

Check the mg of the chemical per ml of medication. I haven’t found 18% available for cats. I did find that strength for rabbits.
