My curtains are destroyed already so it's not for that. I am afraid that they will ingest the cloth material when they are ripping them up.
Plus there are those little hook thingies that are real sharp. They could get injured real quick.
I don't trust Skittles with ANY fabric, unsupervised. With his little 'fetish', I'd probably end up with little fabric conure eggs hatching fabric conures on the 21st day.
The hook things are metal and in the shape of a capital U.
The connect the fabric curtain with the plastic eyelet that runs along the curtain rod. The base of the U is very sharp so it can pierce the fabric if the curtain.
