We cruised for a year with a cat. We modified the area under the 'V' in the v-berth. We put a hooded version under there to keep litter from being kicked out. I wish I would've taught her to use the head. It would've been time well spent. We were always sweeping and it kinda kept me from going barefoot because I hated stepping in it.
story about the cat, she got sea sick all the time. The rougher the weather
, the more puke. We'd measure the weather
by how many piles there were. We'd say "It was ony a 2 puker. Weather was good." or "Man, that was a rough passage
, it was a 6 puker!" Other cruisers got involved in the lingo and we laughed about it the entire coast. My wife loved it...yeah.
