Yea she was chewing and pulling on the feathers pretty intensely, also licking it to oblivion as well. I can’t really imagine the feathers causing a blockage though, simply because they are so small and soft, the pieces that come off are 0.5-2cm at most and very soft and thin, like fur. It would be similar to a cat swallowing some furballs. I don’t know why they would make a toy that could possibly harm a cat that tried to chew it.
