Hello, my cat souty has had a chunk out of his tail near the base of the tail. I've taken him to the vets and they are going to cut some of the skin of from his back and move it forward over the wound then stitch. Firstly, what are the risks he will die under the anesthetic he's 7 years old and his healthy and hasn't eaten for about 15 hours. Also the vet seemed confident he won't have to lose his tail but I'm still worried his tail is mobile and he's moving it around a lot I'm just very worried he's having the operation around mid day. Thank you x
