My parakeets enjoy these and it really helps cut down on moulting. They are easily attached to the cage.

Pros: Non messy, birds like them, easy to hang

Cons: None

I never thought of putting these outside. I will get some more. Pete just loves them.

Pros: easy to hang up. taste, treat

Cons: none

I KNOW THIS IS FOR INSIDE CADE BIRDS BUT I HAVE PUT IT OUTSIDE ALSO AND THE CHICK-O-DEES LOVE IT.
GREAT PRODUCT.

Pros: THE BIRDS LOVE THIS TREAT

Cons: NONE

My 'keets loved treats, so if they weren't as interested in the seed used for added supplements during molting, I could put these in their home with no doubts that they'd eat it up and get the added help they needed during molting seasons. Inexpensive, easy to use, and no product wasted.

Pros: Seen as a treat, they'd eat this without delay

Cons: None

Based on the other reviews, maybe I'll give these another chance. Mine fell apart almost immediately, with large chunks falling down to the cage floor.

Pros: Tasty

Cons: Fell Apart in Large Chunks
