I apologise, but I must concur.
I have a female Flemish Giant approaching her fourth year with us. She is beautiful and I love her dearly. She's my Fuzzy Face Bunny Girl. But there's a catch. She has chisels in that fuzzy bunny face, and they are one of her only ways of getting your attention if you're ignoring her.
It took me two years for us to get to the point where she didn't feel she had to nip me to get her point across. That was before, during, and after her discovering that she
loves skritches. Apart from administering eye drops (which we had to do pursuant to an eye injury that has left her scarred and part-blind), skritches are, as near as she can figure, the reason humans evolved fingers. And toes. She just purely
loves toe skritches. All the skritch, none of the commitment. It's a little awkward while I'm making my
coffee and she shoves her nose under my tapping toe. While I'm trying to stand. And when she starts licking my feet, not only does it tickle, as do her whiskers, it's downright freaky, because there's no way I'm going to forget she's got those chisels
right there.
I have a scar from a scratch on the back of my left hand where I intercepted a gentle reproof from her of my toddling niece. I'm sure the bunny's paws would have hit her in the chest, knocking her onto her bottom, but I didn't want to take chances and taint the kid's view of bunnies.
They are absolutely worth their weight in fertilizer gold every day. We use wadded raw or recycled (both clean waste stream products) paper bedding, which combines nicely with our kitchen scraps to produce an environment almost designed as a worm bioreactor. I haven't bought soil as garden amendment since we got our bunny.
But she's very social. She free-ranges in the kitchen while we're not home or busy, and gets access to the rest of the house when we're home. She seeks attention as I described above, but oftentimes, she just wants to be in the same room with her people. I think it would kill such a rabbit to be alone in a hutch away from people, and if they were people-acclimated, the company of other rabbits might be insufficient, or an unforgivable insult redressable only in bunny blood (you think I'm kidding. Bunny vengeance is no laughing matter. Mizzou would rip the nose off an intruding bunny, and then thump at me until I took away the corpse and cleaned up the blood).
As to Angora specifically, they are not a pet forgivable enough to entrust to a child in a scenario where you "inherit" them; they will be dead before you notice the child has spaced out for a half-day. The reason they need daily attention, if not twice, is that they eat their fur when grooming, leading to something called fur block. We dry papaya and
feed it to ours to prevent such issues (there's an enzyme in papaya that breaks up fur block and prevents the conditions that cause it), and we've been fine, but Angoras are a different creature entirely.
The dog situation is just unfortunate, but honestly, never take a dog whose genetic inheritance involves seeing, chasing down, and killing a prey species, then put the two together and expect the dog to ignore what all their senses and instincts are urging them is appropriate to do, and be surprised when the dog does as the dog was bred to do. Sight hounds aren't LGDs, or even herding dogs.
As to profitability, I love the angora fibre farm concept. If I can work it in to my own plans, I intend to. But from everything I have read and everyone I have spoken to on the subject of raising rabbits, the reason they are profitable is the feed-to-meat ratio. The money is in the meat. Fibre is a niche to be exploited, but I am having a hard time justifying it in any other context than to augment a sheep and alpaca fibre operation.
I would suggest a livestock guardian puppy. If a cat, I would suggest a Maine Coon, because they are most doglike, but their feces still qualifies as biological warfare, whereas dogs' is just unpleasant, on the scale of human or pig. It could be sold to your child as an upgrade to the bunny concept, and would be much more resilient of the attentions and attention-span of a six-year-old.
If you want to get your child used to life cycles and responsibility in a way that would prepare her for bunny care, you could start with
chickens. They're almost dinosaurs. It's not going to be as much of a betrayal to be pecked by an obviously sharp beak as it will be to be nipped with bloody sharp chisels from behind fuzzy bunny lips and whiskers.
Finally, if you wanted to experiment with the idea anyways, I think the ideal mix for a home bunny that produces fibre is an angora/Flemish Giant cross. I lthink the French Angora is larger, but a British would do as well. I think the fibre quality of the French is superior, though. In any case, you'd essentially have to undertake the breeding yourself, and then select only the ones with the appropriate hair traits, and hope that some get the intelligence and inquisitiveness of the Flemish Giant that might make for good companionship. I think it would be desireable to gain the human socialisation and frame sturdiness of the Flemish, and size, to be sure, because I see incorporating them as free-range bunnies that get daily grooming into a bunny-proofed house as the best way to keep them groomed enough so they don't choke on their own fur without confining them in hutches.
Oh yeah, I don't know if you were aware of this, but it is generally recommended to feed a rabbit 1 cup of dark, leafy greens (iceberg is poison, all filler, no nutritional value) per two pounds of bodyweight. My rabbit is around 14 lbs, so we feed her a seven cup head of romaine a day. That's in addition to three tablespoons of pellets and all the
hay she wants. Unless you're set up to grow it yourself, keeping healthy rabbits can be costly.
I mean not horse costly, or even pony costly, but not free. And they're not really suitable for children. They are prey animals, and so purely
hate being picked up and cuddled; it literally triggers "I am about to be eaten" instincts. These are animals that can have a heart attack and die if you turn them belly-up. If your intent is to teach your child the fragility of life, rabbits are a terrific choice, but not so if you wish to instill warm feelings and happy pet memories.
Again, sorry to be the bearer of the news you least wanted to hear. Rabbits are temperamental and delicate, and they don't spare the whip when they're training their human chattel (like most pets, they own you, don't kid yourself). But let us know how it goes. I wish you the best of luck.
