Marshfield Parks and Recreation Department Announces the Passing of Thunder at Wildwood Zoo

Monday, February 26th, 2024 -- 1:00 PM

It is with the utmost sadness; the City of Marshfield Parks & Recreation Department announces the passing of Thunder, the geriatric male cougar, at Wildwood Zoo.

Thunder had struggled over the past few months with hepatic lipidosis (fatty liver disease) and the time came when he was no longer able to be kept comfortable. He was humanely euthanized as a quality-of-life decision after much consideration by his veterinarian team and zoo staff.

At nearly 16 years of age, Thunder had far surpassed the average lifespan of 12 for male cougars under human care. For the past several years, he had been being managed for a variety of age-related ailments, including kidney disease and arthritis.

Thunder arrived at Wildwood Zoo in 2008 with his sister, Star, who continues to reside here at Wildwood Zoo. They transitioned to their new exhibit in 2019 and could often be found lounging in the sun or enjoying their enrichment items.

The zoo will be much quieter without his loud purr and chirps every morning. He was a favorite by many for his majestic looks and sweet demeanor with a flair for the dramatic. He will be deeply missed by all.

Star is currently doing well but will be closely monitored and supported by zoo staff as she makes this transition. As always, the Parks and Recreation staff appreciates your continued support of Wildwood Park and Zoo.
