On the boat we have several pets. No space, but several pets.
Two of these are the bunnies known as Worthington (stoic, brown, slightly wasted, kinda like Vincent Vega in Pulp Fiction) and Emily (blonde, flighty, buxom, and kinda like Diana Doors).
My views on vegetarianism not withstanding I have to say, house (or boat) rabbits make excellent pets. They make even better casseroles but they do make great pets. They’re not noisy, they ‘cuddle’, they’re cheap (except when they need a vet but that’s what pet insurance is for) and they don't need regular walkies or major coordination if you're going away for the weekend.
A home does need a degree of bunny-proofing to stop sharp teeth nibbling through electrical cables etc., but once they’ve ‘been done’ they (allegedly) whiz in a littler try no problem and (allegedly) stroking a bunny slows the heart rate.
Jema ‘loves’ her rabbits. They are the be all and end all of her very existence. They are the alpha and omega of her day.
If you want to know if a house rabbit is the thing for you, may I humbly recommend the invaluable House Rabbit Handbook: "How to Live With an Urban Rabbit" (or, more accurately: How I Learned to Stop Worrying About Animal Faeces and Live Without Skirting Boards) by Marinell Harriman, plus The House Rabbit Society (who also do a fine range of 'rescued' rabbits that need a proper home). If you decide to go for it they are great and rewarding (but, as a committed cat owner, no substitute for a real pet)...
