I can't sign the petition as I'm in Ireland
But I found this page on my travels
https://www.facebook.com/SarahsRodentSanctuary and noticed in one of the pictures there was fluffy bedding being used in a Robo's cage.
I hope the lady didn't think I was being rude at all but I messaged her advising her of the dangers of the bedding. Hopefully she'll take it on board!
