but if you cannot afford $80 then try this one which you can hook up to flat copper plates the cats can stand on while you pet them and they don't know they're being zapped - or - for wild and feral cats who will not allow you to put a collar on them:http://www.zapperplans.com/readymade.html ($10 mini zapper) (copper plates you must purchase or get separately and don't come with the zapper, the copper plates is just an idea of how you can zap the wild/feral cats).
...But for wild and feral cats who won't let you get near them to put a collar on them, you will have to use the plate type and they are great to use for my feral cats, I don't have to irritate my cats by holding wet copper handhelds to their ears or stomach for 3 cycles! This way the cat just stands on the copper plates, and yes they will have the wet paper towels, but the cats don't seem to mind, especially if you are feeding them.
AND I found PARALIXER made by KING BIO - it is clear, odorless, tastless basically and you just add a few drops to the cat's water and take it from me with 13 very smart cats who can taste any kind of herb or medicine "hidden" in their food no matter how small: so far they do NOT notice the drops of Paralixer in their water and are lapping it up no problemo~ THIS is the answer to the parasite cleansing for most cats who simply will not be tricked into ingesting cloves which can be smelled a mile away even by us humans! Here's the links:
So there you have it. If you own pets and want to not only cleanse yourself of parasites but your pets too and your pets happen to be very street smart and/or pretty picky, then PARALIXER and ZAPPER FOOT PADS seem the best way to go.
I just bought the Ultimate Zapper so I will keep that one for myself, but I'm currently saving up the cash to get the ParaZapper with the copper plates or the AutoZapper with the Alligator clips to use with alumuninum foil or metal plates. so I'll keep you posted on the results!
