The FURminator Nail Grinder for dogs and cats is a lightweight, cordless grinder that files and smooths nails with ease. This compact, 2-speed grinder features an easy-grip handle for safe, secure trimming and an LED light that illuminates the nail. An anti-microbial plastic finish helps keep germs and bacteria to a minimum. This tool includes two replaceable grinding bands (additional replacement bands sold separately) and 4 AA-alkaline batteries. Replace the grinding band when it appears worn or when it becomes more difficult to file your pet's nails. Pets need their nails trimmed on a regular basis, usually monthly. Untrimmed nails can affect the comfort and overall health of your pet. Untrimmed nails can cause pets to develop sore feet, legs and hips, well as general discomfort.
