Application: open, reinlegen hay, can make animals.
Our guinea pigs (in 2 groups) each nibble always decent when viewed through us, but we go out of the room, place them with joy in the hay in the rack and hold it their Mittagsratz. Even some big animal is suddenly athletic when it comes to jumping into Heuglück. Certainly falls times of hay on the floor, but in the face of sometimes quite crumbly Industrieheus that's no surprise - and observed in all hay racks. (Is honestly not a problem, hay should always constantly refill or replace.)
Compared with other suppliers, this model is clearly the best at Trixie, this process great. For longer shelf life best seal the legs with toy paint that animal urine does not ruin the whole product within months.
