Thank you for your question. The noise level of this grinder is going to depend on what speed you use it at. The variable speeds make it nice because if you have a pet that is bothered by noise, you can use a slower speed that is going to be quieter to keep your pet calmer. The video for the product does show it in use, which may be the best choice to judge for yourself if it is too loud for your pet. If you would like to watch the product video, you can either click on it on the product page (located below the main product image) or I will attach the video from our Youtube page so you are able to watch it here in my answer.
