the theoretical natural healthcare model goes something like this: when the animal (human or cat) has reached homeostasis and is REALLY WELL parasites will no longer find it attractive as a host and they will vacate............

my paleo-dog has tape worms and other stuff so besides a species specific diet, he is getting a homeopathic workup and herbal/supplement therapy. I am covering all the bases to get him well and absolutely expect his problems to vanish some day!!!! 

How long has kitty been on a proper diet? Do you still feed commercial food? 

As for the heretic (LOL) who said that medicine may be called for.........make sure you have exhausted all NATURAL solutions first. Often people think they have but really haven't. Herbal wormers are very effective. Find a holistic vet to identify the creatures and then go for it! My personal vote would be ground pumpkin seed and black walnut hull extract( blekkkkkk)!

Good luck,

p.s. ginny, what is the "advanced BARF list" I used to be on the "regular" one and prefer my breed-specific Natural-Akita for information savvy.
