Staff and patrons of Assiniboine Park Zoo are in mourning after the death of a young red panda cub.

Little Red, as the cub was known, had suffered from pneumonia "along with other health challenges for several weeks," the zoo says in a post online.

The zoo announced the cub's death on Monday in the same post.

"It’s with heavy hearts that we’re sharing the news that Little Red passed away over the weekend."

The zoo had been posting updates on the cub's health struggles for a few weeks. Veterinarians at the zoo had tried a number of tests and procedures to help the cub.

"We’d like to thank everyone for their messages of support for Little Red over the past few weeks," the post says. 

"Our dedicated veterinary care team did everything in their power to help the little guy. Please help us in sharing your condolences with Little Red’s immediate care team."

Hundreds of people have commented offering their support and condolences.
