If you love cats, then you MUST visit the Cat Boat here in the 'Dam on the Singel - populated with up to 50 rescue cats of all shapes, sizes and ages, it is a feline lover's paradise. This is a working cat rescue centre and not strictly a tourist attraction but it has become part of Amsterdam sightseeing. Lovely staff and a really relaxed atmosphere to escape the hustle and bustle of the rest of the city centre....There are queues sometimes as it is so popular and it only opens for two hours per day so ensure you have the correct times to avoid disappointment. On entry, you donate voluntarily as there is no mandatory admission fee. Donations help to keep this place going and they are much welcomed. You can also buy merchandise, tote bags, postcards and other small novelty items here. Do not miss it.
