As a seasoned pet parent, I’ve always had cats and dogs (and one hamster), but never one of what I’ve deemed “cool” pets, like a rabbit. I didn’t even realize that some of these adorable herbivores came in multiple sizes, like small, medium, large, and for one of these bunnies, giant!
LouLou is a Flemish Giant Rabbit, whose sheer size is jaw-dropping. This very big boy gives Bugs Bunny a run for his cartoonish money.
The humongous gray bunny is bigger than small dogs, cats, and in my opinion, human toddlers. He’s cuddly soft and a stunning sight for someone like me who never knew something so storybook-like existed. According to Oxbow Animal Health, theGuinness World Records holder, a Continental Giant Rabbit named Darius, grew to be 4’3″ and weighed nearly 50 pounds!

How Big Do Flemish Giant Rabbits Get?
Rabbits like LouLou, who are one of the 13 largest rabbit breeds, are known as gentle giants of the domestic pet rabbit world. Typically, they can grow to be upward of 4 feet, weighing 15 to 20 pounds. Much like that of a beloved dog, Flemish Giant Rabbits have an 8- to 10-year lifespan, providing years of devoted companionship.
As an easy-to-train, generally friendly pet, their size may be the first thing you notice, but they have a lot more going on than many realize.
Do Flemish Giant Rabbits Make Good Pets?
These big babies make amazing pets for families with children, thanks to their calm, patient, and docile temperaments. Not all rabbit breeds enjoy being handled much, but these sweethearts are so laid-back and easy breezy, cuddling is in their nature.
Size may be the first thing you notice, but bunnies like LouLou are also highly social and like plenty of time out of a cage, which makes them the perfect addition to any home looking to add a furry buddy to the mix. And bonus: They can be litter-trained like cats, so cleanup is no big deal.
LouLou made his debut on social media, surprising those like me who never knew about this amazing breed. Now that I’ve seen one of these gentle giants, I’ll never look at bunnies the same way!
