Dr Mercola Natural Flea & Tick Defence for Dogs & Cats is a safe, natural pest deterrent that fits the bill.
Here are the natural Brazilian oils and ingredients found in Natural Flea & Tick Defense:
It's not the individual elements that make Natural Flea & Tick Defense so effective, it's the expert blending and balancing of the Brazilian oils with the pure water. This is what distinguishes a natural effective product from just a natural ingredient.
Results from a 2006 study did show how the Natural Flea & Tick Defense formulation was well tolerated by cats. This is a very important distinction for this product.
The natural Flea & Tick Defense formula of natural oils (in spray and wipes) from the Amazon rainforest more than satisfies my selection criteria for a safe and natural pest deterrent for your pet.
