At the Big Bear Farm Zoo Park, a tiny zoo in rural Pennsylvania, 4 bears were suffering in secret for years.

The zoo closed in 1995, but before that Fifi, Bruno, Pocahontas and Marsha had entertained visitors by performing cruel tricks, like riding a bicycle or walking on their hind legs.

When the zoo closed, the crowds left but the bears stayed behind. For more than 20 years they were kept in tiny cages with concrete floors and only a small wooden doghouse for shelter.

Forgotten and alone, the bears learned to cope with their awful conditions, but their health suffered.

It took more than 2 decades of waiting, but help finally arrived to rescue these animals.

The awful conditions at the zoo left each of the bears with painful injuries and disorders. The bears were all mangy and underweight, and even suffering mentally from their isolation.

Fifi, one of the oldest bears, had a bad case of arthritis in her back legs that went untreated. Worst of all, the zoo's owners didn't let the bears hibernate during winter, keeping them awake in spite of their health to host shows year round.

It was a painful and tragic existence, but after 20 years PETA stepped in gave these animals the home they deserved.

The 4 bears were moved to the Wild Animal Sanctuary in Colorado, a much nicer home with wide open spaces to explore, underground dens to hibernate in and vets to care for them.

But Fifi was most excited by the bathtubs, running out of her cage as soon as it opened to soak her tired bones in the water.

The best part of the bear's new home is the animals get to interact with each other. Imagine being locked up alone for 20 years, it's enough to drive anyone crazy!

You can tell just by looking at her how much happier Fifi is:

There are over 1,000 bears living in captivity across America, and not all of them are as lucky as these ones.

The way Fifi and the rest of the gang were treated isn't just awful, it's actually illegal under the Animal Welfare Act.

It's great to see these bears get their happy ending, hopefully more animals will soon!
