The Moncton SPCA usually has too many cats and dogs, but the shelter is currently overflowing with another furry creature —rabbits.

Rabbit cages are perched in the cat room, in an office — anywhere there's space, said director Nanette Pearl.

She's trying to figure out the reason for the population explosion.

"I hope it's just a fluke, but I do believe that people tend to adopt these little guys, or purchase them and take them home and really not understand the amount of commitment, care, finances, everything that requires for the care of these little guys," Pearl said.

Rabbits are also a long-term commitment, with a life expectancy of between eight and 10 years, she said.

And, unfortunately, they're not popular when it comes to pet adoption, said Pearl. "We may or may not be able to find them a home, depending on their temperament, health, age."

So with limited space and money at the shelter, some tough decisions will have to be made soon if the rabbits aren't adopted, she said.

"We do the best we can, but again, there is no guarantee that they will be able to leave here happy."
