I practice “wrap the cat in a towel and wear leather gloves” method of deworming. My cats hate the medication. Even though they are on flea medication (Frontline) year round I still worm once a year.
I heard that there is a new topical medication(on the skin) just released for deworming. Has to be better than my method, which means picking up little pieces of the medication they hack up on the carpet. Ick.
If I’m not mistaken strategic deworming means continuing to worm a cat for prevention.
But right now our main worm problem is with the goats, the little critters are getting immune to all the chemical warfare agents and the vets are not sure what to do.
