One staff member whos particularly fond of Elwood isChantel Trollip, who works as a pathologist at the hospital.
It even has its own call code on the back.
I was actually having a case of the sads' that day, Trollip tells my Modern Met.
But seeing his ID badge turned my whole mood around!
While its not clear who made the ID badge, it looks hilariously official.
I think any potential criminals are thwarted by his sweetness when passersby see him, says Trollip.
The conscientious kitty comes to work every day, and he takes his job pretty seriously.
He is on the security team after all, has to double-check everyone coming and going gets checked.
Unsurprisingly, Elwood is one of the most popular staff members at the hospital.
Hes all we talk about!
Even the regular patients know him by name now, says Trollip.
Its so nice to see him and pet him on our way in or out from work.
