Plastic galley pots / coop cups that hang on mesh or cages / pens. Ideal for grit, treats or water.
These are exceedingly handy to hold those little extra treats you give your parrots.Would certainly recommend
I find these pots much better to use them some feeders. The hold a substantial amount of seed/water. They also stop the birds from trying to kick out the seeds, grit what ever you put in them. Easily cleaned and very sturdy.
