Thank you for writing me back so quickly, unfortnately while I was sleeping last night my cat had chewed the end of his tail off. He chewed off almost 2 inches and when I woke up this morning it looked like a massacre had occured in my house. There was blood all over the place. He is in sugery at the moment and if all goes well he should be able to come home tomorrow night. Thank you for your answer and your concern.
