A cat that has undergone an orchidectomy should be kept indoors and calm for seven days after the surgery. The cat should be prevented from licking its incision, and should have its surgery site checked daily so that potential problems may be prevented or detected early.
Complications are rare in male cats, but may include bleeding at the surgery site, bruising and swelling, infection, and self-induced trauma caused by the cat's licking of the incision. If the post surgical instructions are followed, most cats will heal very easily and quickly.
