DIMETHIcare by Beaphar is a natural and non-chemical remedy against parasites. The liquid in the pipettes contains the silicone dimethicon. This substance forms an adhesive layer around parasites such as ticks, fleas, mosquitoes, mites and lice. This stops these unwanted visitors from moving and eventually they will fall out of your cat's fur on their own. The aloe vera in DIMETHIcare has a soothing and caring effect. One pipette works for 8 to 10 days.
