I noticed others saying you need to hang these by a perch, but my birds really don't care if there is a perch or not, they will simply perch on the cup itself. I will usually however, hang these on the side of the cage just above a side perch up near the top of the cage and like the others, use them for special treats like boiled eggs with the shells mashed in.

I have a bunch of these around. Occasionally I will hae to replace one when I break the wire out of the plastic due to my own negligence, but they are pretty sturdey.

The wire holders are deep enough so they will fit on any cage bar size and interestingly, although I have birds that love to dislodge the food bowls and throw them around, they don't seem to do that to these, maybe because the wire holders are deep enough to discourage it.

Great product, and inexpensive to have a bunch around.

Pros: Easy to clean, easy to hang on any cage and bar size

Cons: none

Little cups like this are perfect for special treats like veggies and fruits. I like to put them in separate dishes so when they are done eating I can just take out the whole cup. I have a ton of these little guys, I usually put them on the top rack of the dishwasher to clean. Just be sure to check the little metal bars for rust after a while.

Pros: Cheap and Easy to Clean

Cons: Not super sturdy

Love these cups. We have several and they are easy to clean and remove to put gravel in them or the birds favorite treat. Just the right size. Reasonable price and durable.

Pros: Great Design

Cons: No Complaints
