Most cats hate water, but not the ones that live in this floating sanctuary in Amsterdam! "The Catboat" (De Poezenboot) is a houseboat full of stray and abandoned cats - and best of all, you can come in and pet the cats!
From Mental Floss:
The shelter was founded in 1968, when a cat lover named Henriette van Weelde purchased a Dutch sailing barge to house the growing number of rescue cats she had taken in. The barge was eventually replaced with the Dutch houseboat that's docked in the canal today. The vessel provides heating in the winter and beds, boxes, and scratching posts to keep cats happy and comfortable. They have access to the outside deck any time of year, and there's even a fence to keep them from swiping at duck chicks in the water.
