The Zeehondencrèche Lenie ‘t Hart, Pieterburen – Netherlands

The Zeehondencrèche Lenie ‘t Hart – Seals’ rehabilitation center
The center rescues seals that have been injured by boats or fishing nets and those that have been sickened
 due to pollution. All rehabilitated seals are released into the wild after their rehabilitation period, 
which lasts from several weeks to a maximum of six months. 
None of the animals remain in captivity and none of the seals are bred. 

I took some photos through a glass window, thus sorry for the poor quality in those images.
