For some rabbits, the world will never be big enough.

It's not enough that Nene has her own blanket. Or her own chair. Or her own room.

Everything belongs to this tiny 2-pound rabbit. Including the hearts of the Montreal, Canada, couple who happen to live with her.

"She owns everything in the house," Derek Rombeiro tells The Dodo. "The house is her playground. She makes everything hers."

And despite being so tiny, Nene won't surrender an inch of her turf to anyone. Unless of course, they come bearing cuddles.

"She stands her ground," Rombeiro says. "No matter how little she is, she will always stand her ground. She is literally the toughest rabbit I've ever met in my entire life."

Six years ago, no one could have predicted Nene would grow up to be a princess.

Much less grow up at all. Rombeiro, who is an animal rights activist and volunteer with local rescue groups, spotted her at a rabbit breeding farm in Quebec. The rabbits were being raised and sold as pets.

She was the runt of the litter. She was riddled with health issues. And her teeth were so crooked they would need to be trimmed regularly for the rest of her life.

It all added up to the farm operator's decision to put the bunny down.

"She looked small and pathetic and in a corner all alone," Rombeiro recalls. "It was either I take her or it was the end of her life."

Rombeiro and his girlfriend Tania Orlando chose to give Nene a real beginning.

And the bunny, who never grew to be much bigger than a handful, wasted no time in seizing the crown.

"She is literally a princess," Rombeiro says. "She cannot be bothered when she does not want to be bothered."

But one thing that does bother Nene are the trips, every two weeks, to the veterinarian to have her teeth trimmed.

"It's very stressful," Rombeiro says. "Rabbits are animals of prey and very stressed creatures."

A rabbit's teeth never stop growing, but normally they file themselves down through eating and gnawing. Because of the particular angle of Nene's teeth, however, that doesn't happen.

If not for a visit to the veterinarian, Rombeiro says Nene's crooked teeth "would never stop growing and they would block her from being able to eat her food. Almost like a rhino but having a horn on his chin."

With the help of a veterinarian who makes every effort to make her comfortable, Nene only feels the slightest pinch of stress during her tooth-trimming sessions.

And then it's back home for some serious de-stressing.
