i know there's been lots of discussion here about how to leave hay in cages for pigeys - all sorts of different ideas for hay storage racks, etc. i've tried several different hay racks, which have worked fine. recently, i ditched the racks, and used a bent grid to make a kind of containment wall in a corner of the cage. i put hay in that corner, on the floor. i just had to share how much my pigs just love having their hay this way!! i put a few handfuls of hay in, an they RUN from wherever they are and literally jump head first into the hay pile and begin munching on whatever hay is around them. it's too funny! it may take a little more time to clean - i remove the soiled hay when i clean their cages twice daily, and there may be some extra waste hay - but it's SO worth it to see how happy they are to burrow in the hay and munch!
