There’s a welcome development in the ongoing recovery of the 5-month-old orphaned cougar cub receiving care at Northwest Trek. Initially facing a high-risk lung surgery after veterinarians discovered fractured ribs and lung damage that occurred in the wild before his arrival, the young cougar’s latest health evaluation brought much-needed good news: surgery is no longer necessary at this time.
During routine pre-surgical checks, the park’s veterinary team noticed signs of natural healing, prompting a reevaluation of the cub’s condition.

“To our relief, his body is beginning to repair the damage on its own,” said Dr. Kadie Anderson, head veterinarian at Northwest Trek. “We’re seeing positive changes, and he’s showing increased strength and energy.”
Dr. Anderson noted that while there’s still a slight chance surgery might be needed in the future, the cub’s prognosis is much more hopeful now.
“We’re cautiously optimistic. His resilience continues to impress us, and we’re adjusting our care plan to support his healing process while monitoring his lungs closely,” Dr. Anderson said.
Another exciting update: the keepers have named the cub Sullivan! The name is linked to strength, intelligence, and power—traits this little guy is already starting to show. He’s certainly proving to be one strong cub!

Rescued by the Washington Department of Fish and Wildlife (WDFW) after being found emaciated and dehydrated in the Spokane area, Sullivan has been receiving intensive, round-the-clock care. Alongside treatments for malnutrition, anemia, and parasites, he is fed a carefully managed diet of ground meat and elk several times daily to help him gain weight.
Dr. Anderson said they are also seeing steady progress in Sullivan’s demeanor.
“He’s still understandably cautious, but he’s starting to show curiosity and more alertness,” she said.

Sullivan remains behind the scenes, continuing his recovery in a quiet, stress-free environment. In the future, guests can see him along the wildlife park’s cat loop, near the bobcat and lynx habitats.
