Anybody out there used this product? My vet & I are looking at treatment options for Howie - who at this time is in fine health regardless of his FeLV/FIV status - just planning ahead. She suggested I check out this site(tcyte.com) - she's never used the product as when it was initially released, it was cost prohibitive for most owners. She wanted to know if I'd be interested in her getting prices etc., but I can't find any independent studies of this product or any owners out there giving it a thumbs up or down for that matter!
