Just an idea about the "felt" substance......about 2 years ago I found a wad of green felt on the floor that one of my cats was playing with. I discovered it had come from the bottom of a statue I had. The cats had knocked it over and there was a green felt bottom on it that was there to protect it from damaging the furnitutre surface. It was rather old and the felt had been coming loose. After they had knocked it over they had pulled at the felt and pulled a chunk off of it and had been playing with it. Perhaps this is where the felt came from at your place.
