The spring grass rack is easy to use. The forage grass can be clamped on the grass rack, so that herbivores such as rabbits, chinchillas, guinea pigs and other herbivores can easily eat the forages, reducing waste and enjoying them easily. The knob is fixed, and the height can be adjusted according to the needs. Not only does the forage feed better, but also reduces the fall of the forage and the effect is good.
