To Whom It May Concern,

I am writing as a concerned Denver citizen who recently visited the Denver Aquarium and was deeply disturbed by the living conditions of the Sumatran tigers housed there. These incredible animals are confined to a small, concrete enclosure with no visible access to outdoor space, natural light, or adequate enrichment. Their current habitat is entirely unnatural and lacks the space and stimulation necessary for their physical and mental well-being.

Tigers are solitary, territorial animals that require large, enriched environments to thrive. At the Denver Aquarium, these tigers are exposed to constant noise, artificial surroundings, and the overwhelming presence of visitors. This environment is not only inappropriate—it is inhumane.

Many visitors share this concern. Numerous reviews on public platforms like Yelp echo the same sentiment: the tiger exhibit is out of place in an aquarium and leaves guests feeling saddened rather than educated or inspired.

If these animals are being kept in the name of conservation or education, then it’s time to reconsider what true conservation looks like. There are far better, more ethical options. Such as the Wild Animal Sanctuary in Keenesburg, Colorado, which offers expansive, natural habitats for rescued big cats. Providing them with space to roam, rest, and live in peace.

I am urging the Denver Aquarium to take action and work with a reputable sanctuary—whether The Wild Animal Sanctuary or another qualified organization—to rehome these tigers to a more appropriate, enriching environment.

Help support this effort and help push for a better life for these animals. With enough support, we can give these tigers the second chance they deserve—one where they can run, play, and enjoy the outdoors, as nature intended.

Let’s do the right thing—for the tigers, and for the many people who believe they deserve better.

Sincerely,
A concerned Denver citizen
