There is no way to predict what your cat's reaction will be. Though in
my experience it is usually favorable.

What is certain, however, is that there will be several messages about
using cats as food, soccer balls, or similar crude suggestions. Odd,
isn't it, that when people query about dogs on board no such comments
are made? But some insecure, arrested development personalities have
negative reactions to any mention of felines.

Cat's have been onboard boats since there were boats. Odds are yours
will adapt just fine.
