Researching doses for Eqvalan/ivermectin for Mr Pompei and came across this really good article (buddy does go on a bit). I have to agree with the article, have used all sorts of ‘stuff’ over the years on my horses, dogs, cats, rabbits, cattle… when it comes right down to it there are no miracle cures or ‘natural’ ways to cure external and internal parasites.
Best way to combat them is through prevention, and if there is an infestation to jump on it immediately with proven treatments. Can’t tell you the amt of money, time, and likely misery to my poor animals I have caused by supposed ‘natural’ miracle cures
These days YES I give my horses phenylbutizon (horse aspirin) for pain, my dog and my horses given Previcox (celebrex) for their pain and I give my Meloxicam (my arthritis and pain med) to my old horse also! We take the same dosage in that one! It has given them many wonderful pain free years of enjoyable life

(shhhh don’t tell but I can get a script for me and give it to her paid by…. Oh never mind bad Kelly haha

). Yep, internal parasites that cause colic? Thing of the past! Ticks on my cat that may cause Lime Disease? Gone woohoo!
So why wouldn’t I do the same for my chickie poos, so Mr Pompei will receive a known treatment to effectively kill his lice infestation immediately and with no risk of toxicity or poisoning. And his misery and suffering with itchy scratchy lice will end almost immediately, and he will be able to join his new harem in a couple weeks hale and hardy

I love modern conveniences!!
