In northern Ontario we need fleece sheets to keep the cold out when it's -40. lol They sell really well here.Are you referring to sheets out of fleece? I am not aware of sheets out of fleece but then there could be.
I remember problems with pj's made of polyester. It was documented that the burns were so much worse because of it melting and adhering to the skin.[We have to thank all the idiot parents who smoke around kids, drop a butt on the kids sleepwear and the fabric melts because it is basically plastic. That is why the government mandated that fleece material have that chemical on it
You are right though, it is very difficult to prove a point. I always hear "I give it to my bird and he is just fine" They don't realise the damage that is being done is gradual. Then people wonder why their bird only last 20 years when the life expectancy is 30 or more.
It is sad, but I will continue to do my research and put it out there, hopefully people will read it and really think about what they are doing to their birds.
Has anyone heard yet what caused the birds to die in Boston? https://www.theguardian.com/us-news/...-unknown-cause
