Wodent Wheel Junior PLUS Nail-O-Matic Jr nail trimmer insert 8 inch diameter (9" tall with stand) small animal running wheel. Includes one Nail-O-Matic removable nail trimmer. The nail trimmer is the only original and patented of its kind. You can tell it's a Nail-O-Matic because of the raised grid paw pad protection. You will see that the patented Nail-O-Matic will be tagged as sold by SunCoast or licensed by SunCoast Sugar Gliders. Accept only the best for your pets! This is NOT the size we recommend for your sugar gliders. Our recommendation for most situations is the SENIOR size wheel, which we also sell. Isn't it a great idea to have your pets nails trimmed while they are having fun? Running wheels are the best in the cage exercise device we know of. The running wheel and Nail-O-Matic are both washable.
