Hi, I have been living on board with cats for 11 years. The 1st cat was the same age as yours and a land animal. The dinghy
ride in the kitty carry cage was the most tramatic as Tom mentioned, if you can put her on board a dock
thats better. We have kept the carry cage on board and it has been needed, so save it.
She addaped very well and we loved having her on board. I put a harness on her and conected a leash to a thrugh bolt and leashed her into the cockpit
when she came up. We still do that with the 2 cats we have on board now. It is cruel to keep a cat on board if they get sea sick. I had one that did and I found a land home for her. We have had a total of 5 cats on board in 11 years. I love my feline friends as crew!
