Hi
What you read on the internet is correct, that it can take months for the end result of nerve damage to the bladder to be totally certain. The tail almost always remains paralysed when the damage is this extensive and most often tail amputation is needed. Bladder function can return totally, partially or not at all depending on the amount of nerve damage. Bowel function can also sometimes be affected. I hope that you have been given the option of helping your cat have a chance of recovery, but its never a rapid process. There's not really any specialist treatment for this kind of damage but good nursing care is really important in aiding your cat to empty his bladder and keeping his rear end clean. It's only really practical if you are prepared to help with all of that.
