A week befor Christmaslast year my cat chewed on a bobbin and got thread wrapped around his tonge. I took him to the vet and $700.00 later he passed the thread. We didn't dare pull it for fear it had wrapped around an intestine. So for 4 days I clipped that piece of thread. I even had to isolate him with his own litter box so I could check the stools. Needless to say, I am very careful about any thread now. Glad yours is alright.
