I am a Transfer Factor user. For myself and the kids!! I actually use the human formula for the cats (I think its 'stronger'). I have friends that swear by this 'miracle' remedy. I know a girl who's cat had FIV and the vet told he he would probably only live a few more months and she started him on TF and he lived a few more YEARS.
Here is information about ithttp://www.shirleys-wellness-cafe.com/tf.htm
And here is where I order mine (the cheapest I've found, with the most pill count (90) ).http://www.4lifeweb.com/pb/index.asp...nguage=english
I told this story in another thread but I'll tell it again.
I had a problem with Saki back in March. He started vomiting for no reason, once a day or a few times a week but he had absolutely no other symptoms whatsoever. Poops were fine, appetite was great, loving and as playful as ever. This went on for almost 4 months. I was just beside myself. He had never thrown up in his 3 years and then he was just throwing up so frequently. It was really upsetting, even though he didnt act sick at all. We did blood tests, urinalysis, tried changing his food ( a few times ) and were going to do an ultrasound and then I started putting Transfer Factor in his food and I dont know if it was a coincidence or what but he stopped vomiting and hasnt vomited once since July. It was absolutely bazar. This stuff is amazing.
And dont bother asking your vet about it because they have always just blown it off (most likely because they cant make any money off you if you go buy a remedy from somewhere else. )
