This is such a wonderful idea .............if folks can live on the houseboats on the canals why can't cats ? So glad that one lady had the means, idea and compassion to establish this special place. Admission is free, donations welcomed and t shirts and other items are offered for purchase. The houseboat is staffed totally with volunteers and visitors are welcome. Most of the cats love to be petted and played with but do be mindful of the signs that describe which cats are not friendly or socialized yet. The cats even have a sun-porch and it was being well used the day of our visit. The cats are also up for adoption so if you live in AMS or the surrounding area, consider adopting one. A visit to the Poezenboot is a must if you love cats. Situated on the Singel canal the houseboat is central to all of the olde town attractions and well worth a visit.
