In shock

The cat is hurt. He got entangled in the central heating with one of his claws, when he jumped off his lookout. I did not hear him scream at first because the window was open and the dust-cart was making a lot of noise emptying the dustbins. He had been hanging headfirst for God knows how long, when I finally came to his rescue! I wasn't surprised when the vet said, he had dislocated the toe and torn the ligaments in it. His 10kg weight had been put on this one toe! The vet gave him a painkiller and we have to go back tomorrow for a check-up. I don't want to think about that something like this could have happened on a working day. He is alone than until the afternoon. I feel bad.
