This Freedom Feeder Trailer/Mini 1 in. Very Slow Feeding Net is designed for the trailer or for daily use with miniature horses, goats, sheep or calves for slow feeding meals. It measures 2.6 ft. x 2 ft. and holds up to 13 lb. of forage hay. It loads at the top, has a drawstring closure and a large carabiner for hanging. Choose from 3 mesh options: 1 in., 1.5 in., or 2 in. mesh openings. 1 in. mesh openings are for insulin-resistant or smaller grazing animals. We recommend that you start transition with 1.5 in. mesh then slow them down further using 1 in. mesh only if necessary. 1.5 in. mesh openings are the most optimal opening to mimic grazing and slow consumption for most horses. 2 in. mesh openings are intended for aggressive eaters and larger horses and you might consider going down to 1.5 in. mesh size once the horse is transitioned.
