Once there were seals

At one time London's Springbank Park had a small zoo with a number of exotic animals. The most popular exhibit was the seal pool. At one point a seal named Slippery escaped from the enclosure, made it to the nearby Thames River and travelled down the river to the Great Lakes. It was captured near Cleveland and returned to its London home. The now famous seal attracted thousands of folk to the small zoo over the following years.

But zoos are no longer the attraction they once were. In fact, today many people take offence at seeing wild animals held in small enclosure and locked in cages. The London zoo was shutdown and the animals sent to other facilities to live out the remainder of their days. 

Unfortunately for the seals, most died in transit. The London seals were true zoo animals, born and raised in captivity. They did not handle being forcibly removed from their London home and placed in small tanks in the backs of large trucks. 

Possibly the trucks were too hot, or the the tanks too small, but whatever the cause, most of the seals died in the backs of those trucks. Very sad. The seals are still missed today.
