Help save little Skittles life

Two weeks ago my most precious baby Skittles became seriously ill and the vets are struggling to understand what is causing the issue. Despite numerous tests and X-rays he has only been give a 50/50 chance of survival. We can however get a better idea of what is causing his illness and restore his health if he gets a CAT Scan. X-Rays are just not enough info.

Unfortunately the only CAT Scanners are in hospitals and as you can imagine, they cost a lot to use.

I'm also struggling to fund his current treatment which has already run into thousands of dollars. I'm even trying to sell household stuff on TradeMe but that process is not working so well.

This has been the most stressful time of my life as this little cockatiel means the world to me. He is my buddy and child. I would really appreciate your help to bring him home to me as a happy and healthy bird. Thank you in advance.
