"I got tired of my tiels messing in their food/water, not to mention knocking the old dishes down. I'm glad I invested in these cups.
The lids do NOT come off, but the opening is very big & they are easy to clean. I love that the rings stay in the cage & the cups just twist & lift out.
The cups are also flat on the bottom and balanced- so they will stand alone on the counter.... which is great since I have 4 to clean every day.
Since they don't 'have' to be hooked over a horizontal bar like the old cups-- I can put their food dishes in new places.
Nice bonus is that I don't have to sweep pellet crumbs constantly! I'm very happy with how much cleaner my floors are now. Cut the crumbs by more than half.
(their seed is in a ceramic crock in the middle of the flight cage; I imagine these cups would help reduce seed hull mess too- if kept low in the cage)
My tiels don't mind eating out of these cups at all... I introduced them to these cups when they were hungry; I dropped a nutriberry in each... they wanted the nutriberries bad enough to be brave. lol.
The medium size is good for cockatiels. 3in wide, 2.5in deep cups. A little too deep if you ask me, but both my birds can get to the bottom okay...
Overall, despite the price, I am glad I bought these."
