This is truly THE BEST pine bark product for your pet! I want my kitty to have the best quality and pure products as we do for ourselves and I am pleased and relieved to have found this pine bark product. It is as pure as they come! No added fillers, preservatives, chemicals, or natural flavoring--nothing but pure and mighty pine bark powder. It even comes with a mini scoop which makes measuring so easy and convenient. My cat took a tumble from the banister in our home and fortunately she had no breaks and trotted away, but a bit later she started having difficulty going down the stairs. We immediately knew from our own knocks and aches pine bark was needed. The challenge was finding one that met our standards. This is it!! She is now running down the stairs again, swatting her balls, doing acrobatics chasing the mouse toy, and kneading the comforter! We have our baby back! Thank you ReNewedPet! She really is renewed, restored, and rejuvenated. I rarely write reviews, but I had to do it for you all because you have an excellent product that helped my pet. KUDOS to the entire team and we appreciate you!!
