I agree, peacock feathers are a DELIGHT for suggies.
But Tiger Lilly insists that I relay this warning: THEY ARE FOR SUPERVISED PLAY ONLY!!! She lost (most of) her tail because one got wrapped around the center axle of the exercise wheel (yes, she still yells at ME too about having the WRONG KIND OF WHEEL in there, etc---rookie's mistake).
Here's a rule of thumb about feathers:
"Feathers from a bird of prey? Suggie says NO WAY!
Feathers from a bird we eat? Suggie says WHAT A TREAT!
Feathers having color or dye? Suggie says DON'T LIE!"
Putting it in human words: Don't use feathers from a hawk, eagle, owl, or other bird classified as a "bird of prey". I also have a policy against using feathers that are red/green/blue (unless Mother Nature MADE them that color). How would you like to find a blue-mouthed glider? No thanx.
Chickens, ducks, geese, quail, pheasants, peacocks (somebody somewhere probably eats them...) are all good for playtime AS LONG AS they're not the short downy feathers...they'd be too easy to be swallowed & choked on.
How to add them to toys
? Quill end into pony beads threaded with thin strips of fleece is a good starter. Use your imagination beyond there!
