I freely admit to knowing very litle about homeopathy, however the ingredients list concerns me slightly:
How much phosphorus is there in this stuff, for instance?
Additionally, the fact that the bottle has a picture of not only a cat, but also a dog, a horse, and what appears to be a parakeet of some sort is kind of worrying. Hardly specialised, you know?
ETA:
The website states that the product works by way of the following:
"We stabilize natural ingredients into our organic oligotherapeutic complex, and then imprint it with vibrational technology to ensure your pet enjoys optimal support for overall health."
They later go on to refer to chelation therapy.
Chelation therapy is the quackery that the Scientologist's Narconon group are currently being investigated over. This was due to the unexplained sudden deaths of various young people who were undergoing Narconon's dangerous, abusive excuses for drug detox programs. Which were based around chelation therapy. Slightly off topic perhaps, but definitely of relevance.
