a duck??? a duck??? why a duck of all things?? xD Rabbit cages..don't they have bars spaced enough that a weasely little ferret could squeeze through? :/ I've seen some ferrets squeeze through some tight spaces before! if they were interested enough, they could get through...
Another thing, most bunnies brought back to pet stores who accept returns, or people's pets they cannot care for, and in spca's and shelters, are the regular bunnies/rabbits... their size, is HUGE. most people see a cute little bunny, think they stay small and forget they get massive....another thing people have to think of. I've seen a 40 pound bunny come back because he was MASSIVE and the family didn't want a big bunny.
To me, because of that, only farms should own big bunnies - or people with large lots. dwarfs can be sold in stores, but that is it.
there are 2 males, 3 years old, in the pet store. they have been there for a month. No one wants the old ones

If I wanted to I'd get them xD but have no room!!
