It wont let me anywhere near it,and if I make a quick grab for it,it pulls along its hanging leg painfully and makes conditions worse,I once tried to reach him calmly and I got hold of him but he bit me hard and I was bleeding.Pls I have to take him to the vet immediately or he may pass out.Let me know a way to make him unconscious maybe something to be mixed with food or something......and pls give me the duration of its effect as I dont want him getting up in the middle of nowhere and getting a shock....right now he's under the refridgerator......Pls help fast,the vet hospital is about to close for the day and tomorrow is a sunday,which means it is a HOLIDAY!!!!!PLS help fast...
