There is a great group of boaters owned by cats on FB: 'Gatos del Mar'. Consider joining that as well. Lots of good info.
Our land cats readily adapted to being full time boat cats on our monohull ketch.
We use (or at least the cats do...) the
Breeze litter system to minimize dust and grit onboard, and so we can pack around a year's worth of supplies in the same space one tub of clumping litter. (And clumping litter in the bilge is a hazard...)
Read our
articles about having cats onboard if you are interested in more details and links to some great resources.
Have fun with your Gato del Mar...
Cheers, Bill
