Orange kitten 'Otter' born without a complete skull gets a titanium implant and wears a custom 3D-printed helmet to purrtect his tiny noggin: 'He now gets to live a long, full life'

Usually, orange cats have plenty of skull but no brain cells inside to protect. For Otter, it was the opposite.

Even after nearly 6 years of being an editor for I Can Has Cheezburger, cats still surprise me. It's not just the heartwarming rescue stories filled with kind people, or the cats that are born with rare fur patterns and unique colorings, but how resilient felines are that gets me. Indoor cats can survive for years being lost outside and eventually find their way back to their pawrents, never once giving up. They can carry a whole litter of kittens in the scorching summer heat, give birth, and then find a way to bring their kittens to a wholesome hooman to hopefully give them a chance to live their best lives.

An Instagram page called @General.knowledge.booster posted Otter's story, and we couldn't resist sharing it with you. Otter was born with an incomplete skull, meaning that part of his brain (yes, he did have one despite popular opinion) was left exposed. Acting quickly, volunteers 3D-printed him a custom helmet to purrtect his tiny head. When he was old enough, he was able to get a special procedure that implanted some titanium to close up his head fur good and keep him safe. Now, Otter is helmet-free and is the happiest little guy his pawrents could ask for.

The life of a cat can be heartbreaking, but it doesn't have to be that way if we use our compassion and hooman brains to intervene. We did that for Otter, and look at him now! He's a fully functioning cat (as much as an orange cat can be), and with a titanium skull that makes him the closest thing to Wolverine we'll have anytime soon. A soft, cuddly, and adorable Wolverine… and we think he should be cast in the new X-Men movie. Just saying.

General.knowledge.booster @this account will boost your knowledge After being born without a skull, cat undergoes titanium surry and receives a helmet to protect its head.

general.knowledge.booster Otter the kitten was born with a rare skull defect leaving his brain exposed. Volunteers 3D-printed a tiny custom helmet to protect him during his early life. Once he was old enough, a neurosurgeon successfully covered his brain and sealed his skull using a permanent titanium mesh plate, allowing him to live fully helmet-free.

We've heard of babies having to wear helmets because their head shapes are slightly off, but never a cat. We've also never heard of implanting titanium into a cat's skull before to heal it. If you told this story to someone 100 years ago, they would have absolutely no idea what you were talking about. Even 60 years ago, this would sound like some kind of sci-fi novel that you invented, but now, it's a reality!

mashvet We received an update on how Otter is doing - "Otter is doing AMAZING!! It's been 1.5 months since his brain sur ry, and I have been astounded by how quickly and easily he recoveredⒸ

Otter no longer has to wear his helmet since he has a titanium skull now! He is the happiest little guy with a love for life and for everyone in it He loves climbing the cat tree (which he was never allowed to do before) and hanging out in the hammock

It's incredible that Otter never experienced any neurological symptoms and a testament to Dr. O'Neill and the talented staff at MASH that his cutting-edge and delicate brain sur ry was so smooth with no complications

Look at that noggin! Good as new - you would never even know that anything was wrong in the first place. See how resilient cats can be? We're sure it wasn't easy, but Otter purrservered, and that's all that meowtters.
